Microsoft finally was able to break through into the smartphone business by introducing their new Windows Phone 7 smartphones in 2010. The comeback for Microsoft was not easy after its attempt and tries with their previous Windows Mobile 6.5 Platform.

The first smartphone to grace the Windows Mobile Platform was Sony Ericsson Aspen with Windows Mobile 6.5.3 OS. After which Microsoft jumped was into building and updating its OS platform for smartphones and finally brought out Windows Phone 7 smartphones in October 2010 at Mobile World Congress in Barcelona. From then on Microsoft was up there along with the big titans like Android, iOS and BlackBerry OS.

The brand new operating system received strong reviews and moderate early commercial success. 7 Series with a completely new home screen along with new interface, improved social networking tools, Xbox LIVE and Zune integration were ready to move on from past.

The home screen consists of 'Tiles' which links applications, features, functions, contacts, web pages and media items wherein users can add, rearrange or even remove 'Tiles'. And the OS is integrated with popular social networks like Facebook and Windows Live, also Gmail is included. Few of the other built-in hubs include Microsoft Office, Windows Phone Marketplace, Games, Music and Video. Another advantage apart from multi-touch (feature which comes close to Apple iOS4) is that the dark theme helps the users to enjoy an increased battery life.

But one disadvantage strikes the OS, as it doesn’t contain universal search option available in iOS, webOS, Android and BlackBerry 6. One more disadvantage of Tiles feature is that it has very limited home screen and customization space compared to Android, iOS and BlackBerry. Apart from these, Windows Phone 7 smartphones won’t be supporting copy and paste out of the box and no third party multitasking of apps. Anyhow Microsoft is bringing a fix for the copy and paste option soon.

The Web browser in Windows Phone 7 is known as Internet Explorer Mobile which is seen as a browser in between IE7 and IE8. And the browser supports 6 tabs, multi-touch gestures, streamlined UI and pinch zooming. The smartphones will receive support for Adobe Flash Player in mid-2011 and YouTube streaming is also available.

When it comes to virtual keyboard it can be compared to Apple’s iPhone and is better than few of best Android smartphones out there. Auto correcting feature is available as one type and will allow the users to change a word after it has been typed by tapping the word.

Ultimately, the smartphones from Microsoft are here to stay and Microsoft has done a good job in terms of navigation, Zune and Xbox Live integration, fast operating system, support for Office and a good email experience. More updates and improved furnishing will be done in near future and the mobile future for Microsoft seems to be bright after its initial failures.
