Microsoft officially unveiled Windows Mobile 6.5 at the MWC 2009 in Barcelona. The new WinMo update looks quite nice and is something to look forward to when it gets released on the first handsets in the middle of this year.
The new HTC Touch Pro2 and HTC Touch Diamond2 will be upgradable to Windows Mobile 6.5. At the MWC 2009 HTC already showed off a Diamond2 running Windows Mobile 6.5. Engadget and Gizmodo published video walkthroughs of the Windows Mobile 6.5 OS running on the Diamond2.
Windows Mobile 6.5 is not revolutionary but it goes with the times and has a great new start screen. In most cases you still get a customized UI on top of it anyway. LG runs its new S Class 3D UI on Windows 6.5 and HTC runs the improved TouchFLO 3D UI.
