The Ultimate Smartphone Shootout – Symbian vs Android vs Windows Mobile vs BlackBerry vs iPhone

want to buy a smartphone. Great choice. Modern smartphones gives you robust email integration, great organization capabilities (notes, calendars et all), great internet browsing experience, and above all, great extensibility through applications. They are mini personal computers that you can carry around in your pocket.
Now, the next question is, which one ? The engine behind a smartphone is its Operating System (OS). This presents you with 5 great choices, each with its own pros and cons.
First lets see a few charts to set the context:
Symbian is the most popular operating system with about 40% share in all handsets sold (as of Q2, 2010). RIM (BlackBerry), Android and iPhone OS follow behind with about 20% share each.

Yet, the developer ecosystems of iPhoneOS and Android are much more active. iPhone OS has the most apps available for it – over 200,000, while Android is second with over 70,000 apps (as of Q2 2010). Such a large range of app availability means that you are never short of new things to do with on these smartphones.
Number of Apps Available in App Stores (Source: Mobile Developer Economics, 2010 and Beyond)
Ok, now that the figures are out of the way, lets hit the road and consider each OS on the 2 most important parameters – user interface (how does the OS ‘feel’), and application availability (i.e. how many applications are available to extend the functionality of the phone – think news, social networking, dictionaries, productivity and other apps).
User interface is more important for most users, so it will be ranked on a scale of 10, while application availability will be ranked on a scale of 5. The sum of these two scores will be the final score for each OS.
Please note that we are only considering the operating systems for touch screens (which form a majority of the smartphones these days) – in fact, operating systems such as iOS (iPhone OS) and Android are designed only for touch screens.
Now, lets look at each OS in detail. If you are interested in only the final scores, skip to the bottom of this article.

Symbian

The oldest smartphone operating system. If you have owned a Nokia smartphone, you are probably familiar with this OS.
Symbian was earlier a separate company but was acquired by Nokia in 2008. Today virtually all Nokia smartphones as well as some of the smartphones from the likes of Sony Ericsson, Samsung and LG are based on this OS. Lets rank it on the important parameters

User Interface (for Symbian S60) : 6/10

How do we put this ? As far as touchscreen phones are concerned, Symbian is robust and reliable, but its not really quite as intuitive as Android or iPhone OS.
Things which would require a 1-2 taps on Android tend to require 3-4 on Symbian with its often redundant sub menus. Still, its pretty solid, and doesn’t take much time to get used to.
Here is a look at the Nokia X6, based on the Symbian S60 Fifth Edition.

User Interface (for Symbian 3) : 7/10

The new version of Symbian – Symbian 3 – available in the newer Nokia smartphones including N8 – revamps the ageing OS a bit, and improves the user interface, bringing in multiple personalized home-screens, pinch to zoom functionality etc, but still falls short of the more modern operating systems like Android in terms of intuitiveness.
Here is a look at Nokia N8, based on Symbian 3.

Application Availability : 2.5/5

Being the oldest among the big smartphone platforms (and the most popular), there is a decent variety of applications available for Symbian. The new Ovi Store makes it easy to browse and download apps straight on your Nokia smartphone. And a renewed push to the developer ecosystem (including introduction of carrier billing in several countries) indicates that Nokia is prepared to give a good fight in the face of hard competition.
That said, however, the variety of applications, currently available, still falls way short when compared to Android or iPhoneOS (see chart).

Android

Anything from the house of Google is bound to generate hype and interest, so in a sense Android was always destined to be successful. But it would be this successful, not many imagined. With great overall performance, and simple, sensible functionality that is the hallmark of virtually all Google products, Android has caught on the imagination of mobile manufacturers like no other OS.

User Interface : 9/10

Android interfaces by the likes of HTC and Sony Ericsson have been praised unanimously as being beautiful and intuitive. Even the plain vanilla interface adopted by some manufacturers is pretty good, and makes up for its lack of flair with simplicity of use.
So Android gets a clear thumbs up here. It would have been foolish to expect anything else from Google anyway – they are great at designing brilliantly usable interfaces.
Here is a video demo of HTC Desire, running on Android.

Application Availability : 4/5

So far the only platform to come even remotely close to challenging the number and variety of apps on iPhone OS, the Android application market has grown by leaps and bounds ever since its release. In fact it gets a leg up on the iPhone app store in terms of the ratio of free applications to paid applications.
Free vs Paid Apps (Source: Distimo Report, Jun 2010)
In fact some of the really good apps for Android are those already on the phone and created by Google itself – the troika of Gmail, Google Calendar and Google Maps, are brilliantly designed and sync flawlessly with your online accounts.
For instance, all your phone contacts are synced with your Gmail contacts, in effect you always have a backup of your phone contacts in your Gmail account, so absolutely no worries on that account, if your phone ever gets lost or stolen.

Windows Mobile 6.5

The mobile OS by Microsoft has been a decent, robust choice for business phones. Although often criticized for a dull interface, recent phones by the likes of HTC have managed to, at least partially, turn that perception on its head, with slick and intuitive interfaces built on top of the Windows Mobile platform.

User Interface : 6/10

Although the Windows interface brings with it robustness, it still fails to match up to the best in class in terms of easy of use.
Here is a look at the Samsung Omnia 2 with Windows Mobile

Application Availability : 3/5

Like Symbian, Windows Mobile has fallen way behind in the app race, even with its head start. Still it has a decent app variety backing it up, and the Windows Market Place provides an easy way to download and install apps.
Of course, one great thing is that Windows Mobile also packs Office mobile, which means you have reading/editing documents, spreadsheets and presentation straight out-of-the-box, which is obviously great if you need access to such files on your mobile.

Windows Phone 7

The most anticipated development in the smartphone market in recent times has been the launch of the new version of the mobile OS from Microsoft. Called ‘Windows Phone 7?, its beautifully designed, and radically new interface has impressed one and all with its focus and simplicity of use. It represents a fresh start for Microsoft in this domain, and the initial reviews indicate that they are right on target.

User Interface : 9/10

Introducing new elements such as ‘live tiles’ (links to applications and features that are dynamic and update in real time – for example, the tile for an email account would display the number of unread messages) and ‘hubs’ (for example, the Pictures hub shows photos captured with the device’s camera and the user’s Facebook photo albums) , Windows Phone takes a new, fresh approach to a smartphone, managing to achieve both functionality and ease-of-use together.
Here is a demo of the Windows 7 User Interface (phones will be commercially launched by the end of 2010):
Application Availability : 2/5
Being a completely new OS, old Windows Mobile apps will not be able to work on the Windows Phone 7. That means the OS has to take a fresh start, and will not have a well loaded app store to begin with. However, Microsoft is pursuing developers aggressively (Twitter, Ebay and IMDB apps have already been developed), and you can expect a lot of action in this space shortly.

BlackBerry OS

The big daddy of business phones – RIM – relies on the sturdy BlackBerry OS to power its handsets. Its strength, like that of the Symbian OS, is more in its robustness, than ease of use.

User Interface (BlackBerry OS 5) : 6/10

Like the Symbian interface, BlackBerry OS is smart, and gets work done, but not as fast, or as intuitively as Android or iPhone OS.
Here is a look at the BlackBerry OS 5 user interface on the BlackBerry Storm 2

User Interface (BlackBerry OS 6) : 7/10

The new version of the BlackBerry OS is a significant upgrade – with a more functional home-screen, social feed apps, a better browser and a more touch-friendly interface in general. BlackBerry Torch is the first phone to utilize it so far, and more phones will be launched shortly.
Here is a look at the new user interface on BlackBerry Torch.

Application Availability : 2.5/5

Again app availaibility is not as great as some other operating systems. But you will certainly find all the major apps there (no serious developer would give the BlackBerry a miss, with its lucrative business consumers). The BlackBerry App World provides easy access to these apps.
Like Windows mobile OS, BlackBerry also usually packs capability for reading/editing documents, spreadsheets and presentations straight out-of-the-box, catering to its major market of business users.

iPhone OS (iOS)

The iPhone was that one revolutionary device that changed the way we looks at phones. Forever. Never had the simple phone been transformed into something so brilliant, and so beautiful.

User Interface : 9/10

Apple is the expert at designing beautiful and intuitive interfaces, and they hit the jackpot again with the iPhoneOS. Successive versions have improved usability even further. Really you have to use the iPhone to grasp the beauty of the software.
Here is a look at the iPhone 4 user interface.

Application Availability : 4.5/5

With the highest number of apps amongst any app store, Apple is the clear leader and offers an astounding choice of apps to iPhone users (see chart). There is an app literally for everything! News, reference, sports, weather, shopping, tv, movies, games, notes, organizers, social networking – virtually every possible category is loaded with hundreds of apps.

Final Scores

Here is a look at final scores.
Smartphone
Operating System
User Interface
(On Scale of 10)
Application Availability
(On Scale of 5)
Total
(On Scale of 15)
iPhone OS 9 4.5 13.5
Android 9 4 13
Windows Phone 7 9 2 11
Symbian 3 7 2.5 9.5
BlackBerry OS 6 7 2.5 9.5
Windows Mobile 6.5 6 3 9
Symbian S60 6 2.5 8.5
BlackBerry OS 5 6 2.5 8.5
The iPhone OS and Android emerge out as the clear winners. Its tough to decide between them, but you can’t go wrong with either of those two. They are both intuitive and well designed. Windows Phone 7 is the new kid on the block to watch out for. It presents a completely fresh, new interface that is great at getting things done quickly, and should appeal to a large segment of users looking for no-nonsense phones.
BlackBerry and Symbian are solid operating systems in their own right, and have large (and loyal) user bases. But in an objective analysis they tend to fall behind a little when compared to the best-in-class. They will need to ramp up their game a bit (which they do seem to be doing with their latest versions), to stay among the top contenders in the long term.
On the whole though, this is an exciting time to buy a smartphone, with a large variety of good products to choose from. And as the competition heats up further, continue to expect a lot more action in this space.

Create A Hidden Folder

This is not a secure hack. It is designed to hide your files from some one who is browsing through files, not your system admin, not your computer hacker friends. Think of it like hiding your money under the mattress, if some one really wants to find it they will, but if they are not looking for it they wont find it. It’s a fun trick and it works best on your desktop (just remember where you placed it)
You ever have a folder on your computer that you really dont want any one to find? You can make this folder hidden but then you have to un-hide all the folders when ever you want to find it. So how can you make a folder truly invisible? Follow these simple steps and your unmentionables will stay that way.

1. Right click where ever you want the invisible folder to be and select create a new folder.

2. Right Click on the folder and hit rename. Erase the name of the folder so there is nothing there.
3. If you try to stop here windows will tell you that you need to provide a name. So to get around this… with the name field still active hold down ALT and press 0160 on the number pad (make sure Num Lock is on), release alt


You should now have a blank name with nothing but a folder next to it
4. Now click on the nameless folder and right click. Select Properties.

5. Go to the Customize tab.

6. Find and press the Change Icon button. Scroll through the icons until you find one that has no image.

4. Hit OK and you have an invisible folder!

With the invisible folder you can hide what ever undesirables you have. Be it video games at work, pictures of your family or anything else you can think of “wink”.
The folder will show up for a brief second if you put it on your desktop. For that reason it might be smart to place it inside a folder or amongst a group of folders.

Happy Hiding!

How To Run Multiple Operating Systems On One Computer


VMware Workstation allows you to run multiple operating systems on one computer. What does that mean? On a Windows XP computer, if you have a lot of memory (I recommend a minimum of 2GB) and hard disk space (I recommend a minimum of 250GB), you can install VMware and it will allow you to run multiple operating systems under your main operating system – Windows XP. What?
For example, let’s say your computer is running Windows XP and you want to run Windows Vista as well to see what it’s all about. But you’ve heard so many horror stories about running Vista that you decide you just want to try it out and not upgrade from XP to Vista. Well, you would download and install VMware Workstation (purchase or download the evaluation version), then create a VM for Windows Vista.
What is a VM?
VM stands for Virtual Machine. A VM acts just like an operating system and it’s installed on top of your main operating system. It is a crazy concept to visualize at first but it works. This also allows you to install many other operating systems as well. Here are some that are supported by VMware Workstation:

  • Windows – Most versions of Windows
  • Linux – Ubuntu, RedHat, SUSE to name just a few
  • Novell Netware
  • Sun Solaris
  • MS-DOS and FreeBSD
Once you have VMware setup and you install, let’s say Windows Vista, you’ll be able to run both your main Windows XP and Windows Vista on the same PC. Here’s a screen shot of Windows Vista – Home Edition, running in a VM on my main Windows XP PC.


Snapshot Manager
A really nice feature of VMware Workstation is Snapshot Manager. This feature allows you to install software that you might want to test but not commit to. For example, if you install Windows Vista in a VM, you can take a snapshot of it to preserve its state – a newly, clean install of Windows Vista.
Then, you could install some software that you want to test and play around with in the Vista VM. Once you’re done, you can use restore the VM back to the pristine install it was before you installed the software to test. This is what Snapshot Manager does. You can branch off in different directions using Snapshot Manager.
Another good example of this is when I wrote about Visual Basic 2008 Express Edition and Visual Web Developer 2008 Express Edition. I wanted to keep the two installs separate in a VM. So after I installed and was done testing VB 2008 EE, I reverted back to before I installed it and then I installed Visual Web Developer.
There are plenty of ways to use Snapshot Manager and I just scratched the surface on using it.
Another great feature is the ability to suspend a VM. If you suspend a VM it saves the state of your VM as is and allows you to shut VMware down. Below is a picture of Windows Vista – Home Edition, in a suspended state in VMware Workstation.

core 2 duo processor

Core 2 is a brand encompassing a range of Intel's consumer 64-bit x86-64 single-, dual-, and quad-core microprocessors based on the Core microarchitecture. The single- and dual-core models are single-die, whereas the quad-core models comprise two dies, each containing two cores, packaged in a multi-chip module. The introduction of Core 2 relegated the Pentium brand to the mid-range market, and reunified laptop and desktop CPU lines, which previously had been divided into the Pentium 4, Pentium D, and Pentium M brands.
The Core 2 brand was introduced on July 27, 2006, comprising the Solo (single-core), Duo (dual-core), Quad (quad-core), and in 2007, the Extreme (dual- or quad-core CPUs for enthusiasts) subbrands. Intel Core 2 processors with vPro technology (designed for businesses) include the dual-core and quad-core branches

Models

The Core 2-branded CPUs include: "Conroe"/"Allendale" (dual-core for desktops), "Merom" (dual-core for laptops), "Merom-L" (single-core for laptops), "Kentsfield" (quad-core for desktops), and the updated variants named "Wolfdale" (dual-core for desktops), "Penryn" (dual-core for laptops), and "Yorkfield" (quad-core for desktops). (Note: For the server and workstation "Woodcrest", "Tigerton", "Harpertown" and "Dunnington" CPUs see the Xeon brand.)
The Core 2 branded processors feature Virtualization Technology (with some exceptions), Execute Disable Bit, and SSE3. Their Core microarchitecture introduced SSSE3, Trusted Execution Technology, Enhanced SpeedStep, and Active Management Technology (iAMT2). With a maximum thermal design power (TDP) of 65W, the Core 2 Duo Conroe dissipates half the power of the less capable contemporary Pentium D-branded desktop chips that have a max TDP of 130W.

CPU Processor Comparison – Intel CPU Processor Comparison – Intel Core i7 vs. i5 vs. i3el Core i7 vs. i5 vs. i3

Intel has now released the new Sandy Bridge architecture, and this has resulted in a re-launch of the Core i3, i5 and i7 brands. Thankfully, this means the i3 vs i5 vs i7 battle is no longer such a nightmare.

i3 vs i5 vs i7: A Branding Dream

Intel's previous Core i3, i5 and i7 branding was a supreme pain in the butt. It was difficult to explain because Intel didn't really divide features along the brands evenly. Processors in the same brand didn't even alway use the same socket. This made explaining the differences between processors extremely difficult.
Now Intel has introduced Sandy Bridge, the new architecture for its processor. It has also re-launched its products using the same Core i3, i5 and i7 brands, but with new products inserted. To represent this, Intel has moved to a 4-number naming scheme, with the processors being numbered 2100, 2500, and etc.
Thankfully, this re-launch has cleared up the product line significantly. The features available on different processors are now much clearer. Let's take a look at what each brand of Intel processor offers you.

Core i3 Series

Core i3 vs i5 vs i7
click to enlarge
Intel's Core i3 processor line has always been a budget option. These processors remain dual-core, unlike the rest of the Core line, which is made up of quad core processors. Intel's Core i3 processors also have many features restricted.

The main feature that is kept from the Core i3 processors is Turbo Boost, the dynamic overclocking available on most Intel processors. This, alongside with the dual-core design, accounts for most of the performance difference between Core i3 processors and the i5 and i7 options.
Core i3 processors also lack Intel's vPro technology virtualizaton and AES encryption acceleration technology. These are features unlikely to appeal to your average user anyway, and are instead targeted towards enterprise users. Still, the lack of these features should be kept in mind.
One feature that Core i3 has - and i5 doesn't - is hyper-threading. This is Intel's logic-core duplication technology which allows each physical core to be used as two logic cores. The result of this is that Windows will display a dual-core Core i3 processor as if it were a quad-core.
Finally, Core i3 processors have their integrated graphics processor restricted to a maximum clock speed of 1100 MHz, and all Core i3 processors have the 2000 series IGP, which is restricted to 6 execution cores. This will result in slightly lower IGP performance overall, but the difference is frankly inconsequential in many situations.

Core i5 Series

Intel used to split the Core i5 processor brand into two different lines, one of which was dual-core and one of which was quad-core. This was, needless to say, a bit confusing for buyers.
Thankfully, the behavior has stopped (for now). All Sandy Bridge Core i5 processors are quad-core processors, they all have Turbo Boost, and they all lack Hyper-Threading. Most of the Core i5 processors, besides the K series (explained later) us the same 2000 series IGP with a maximum clock speed of 1100 MHz and six execution cores.
In the i3 vs i5 vs i7 battle, the Core i5 processor is now obviously the main-stream option no matter which product you buy. The only substantial difference between the Core i5 options is the clock speed, which ranges from 2.8 GHz to 3.3 GHz. Obviously, the products with a quicker clock speed are more expensive than those that are slower.
NOTE: As of 2/20/2011, Intel has introduced a dual-core Core i5 called the 2390T. The T appears to be what designates it as a dual-core part. It is the only dual-core Core i5 as of yes, so hopefully Intel has introduced this as some sort of exception, as a return to the confusion of the first-gen Core i5 parts would be disappointing.

Core i7 Series

The Intel Core i7 series has also been cleaned up. In fact, it has perhaps been cleaned up too much, because at the moment Intel is offering only two Sandy Bridge Core i7 processors.
These processors are virtually identical to the Core i5. They have a 100 MHz higher base clock speed, which is inconsequential in most situations. The real feature difference is the addition of hyper-threading on the Core i7, which means that the processor will appear as an 8-core processor in Windows. This improves threaded performance and can result in a substantial boost if you're using a program that is able to take advantage of 8 threads.
Of course, most programs can't take advantage of 8 threads. Those that can are almost usually meant for enterprise or advanced video editing applications - 3D rendering programs, photo editing programs, and scientific programs are categories of software frequently designed to use 8 threads. The average user is unlikely to see the full benefit of the hyper-threading feature. In the Core i3 vs i5 vs i7 battle, the i7 has limited appeal.
The IGP on Core i7 processors can also reach a higher maximum clock speed of 1350 MHz. As I've said before, however, this difference is largely inconsequential when measuring real-world performance.

Can you create a folder named "con", "prn", "nul" in windows

Can you create a folder named "con" in windows?? Also try to create a folder named "nul" you won't be able to. If you are not tired, also try creating folder named “prn“. I hope you could create, oh you could not??? Yes, there is a reason.

This is because “nul”, “prn” and “con” are “special” files in Windows System that are used in maintaining the internal directory structure in the FAT (File Allocation Table).


How to make it ????
Basically CON, PRN, LPT1, LPT2, LPT3 are folders which are reserved by Windows, you can't create it easily. So if you want to create any folder with these names then :

Rename the folder
Type CON , then press & hold Alt key & type 0160
Leave Alt key now.

So in this way you can make any folder with these names.
