As was widely rumored, leaked, and predicted, Microsoft made a series of announcements regarding its Windows Mobile platform at the Mobile World Congress (MWC) 2009 in Barcelona on Monday. CEO Steve Ballmer proclaimed that smartphones would soon comprise 50 percent of worldwide mobile phones and that Windows would be the platform that would continue to be adopted not only on the PC but on mobile devices as well. As part of the various announcements relating to devices, software, and services, Ballmer unveiled Windows Mobile 6.5, Microsoft My Phone, and Windows Marketplace for Mobile. To simplify things, the new Windows Mobile phones would start to be marketed as "Windows phones" in the fall, which is when the new devices from Microsoft partners will begin to ship.
Windows Mobile 6.5 includes a new home screen with customizable widgets that display glanceable updates from users' favorite Web services and let users tap into them quickly, along with faster, more efficient access to personal e-mail, work e-mail, phone messages and instant messaging. It also includes an improved touch-screen interface, making it easy to take action with a finger, and an updated version of the latest Internet Explorer Mobile browser, which in a third party research study by sponsored by Microsoft, supported execution of up to 48 percent more assigned tasks than the other browsers and phones studied.
