Microsoft Windows Mobile is a mobile operating system developed by Microsoft that was for use in smartphones and mobile devices but is being phased out to specialized markets, the current version is called Windows Mobile 6.5, it is based on the Windows CE 5.2, kernel and features a suite of basic applications developed using the Microsoft Windows API, it is designed to be somewhat similar to desktop versions of Windows, feature wise and aesthetically, additionally third party software development is available for Windows Mobile and software applications can be purchased through the Windows Marketplace for Mobile. Originally appearing as the Pocket PC 2000 operating system most Windows Mobile devices come with a stylus pen that can used to enter commands by tapping it on the screen, Microsoft announced a completely new phone platform, Windows Phone 7 at the Mobile World Congress in Barcelona on February 15, 2010, phones running Windows Mobile 6 will not be upgradeable to version 7.

Windows Phone 7 is a mobile phone operating system developed by Microsoft and its is the successor to their windows Mobile platform, it is aimed at the consumer market alternatively the enterprise market like its predecessor, it launched in Europe, Australia and Singapore on October 21, 2010 and in the US & Canada on November 8, 2010 with Asia to follow in 2011 with windows phone 7, Microsoft offers a new Metro user interface, integrates the operating system, with Microsoft’s other services.

Windows phone features a new kind of user interface which is based upon Microsoft’s Windows phone 7 design system, the home screen called the start screen also, is made up of tiles, they are links to applications, features, functions and individual items like contacts, web pages, applications, media and other items, users can add, remove and rearrange tiles.

Tiles are dynamic and it updates in real time like the tile for an email account would display the number of unread messages or a tile could display a live update of the weather.

I would not say that it’s a real contender to the iOS and Android just yet because there are still some features are missing in Windows Phone 7 which makes it incomplete but Windows Phone 7 is indeed a refreshing experience from the seas of icons in the iOS and Android Phones, last time success is measured by units shifted and now success is measured by the number of applications, games and developer headcounts, that is why the iPhone, iOS and Google phones keep on saying that they are catching up in a bizarre number, Nokia has announced just last week that they have attracted some 4,00,000 new developers over the last years, now you see that every Smartphone company is using applications as the measuring unit.

Now Microsoft’s new contender might be a new company, but it also wants to show off a bit among the older companies of touch screen, it has now about 15,000 Windows Phones developers signaling their intent to bring exciting content to Windows Phone, enough implied manpower to push well beyond the 3,000 applications and games expected to be populating the Windows Marketplace by the end of this week.
