"I think the intent of the Windows Mobile 6.5 release was to provide a more finger friendly user interface on touch screen devices, while non-touchscreen devices remain pretty much the same. I believe there were some backend updates and improvements, but there were not readily apparent. There are four main areas where end users will see changes and these are in the Start menu, lock screen, Today screen, and menus. Let's check out each area in more detail."
My friend the hyper-productive Matt Miller - seriously, how DOES he do it? - has his take on Windows Mobile 6.5. And it's about the same as most of the other reviews we've seen today...there's a general feeling of "Really? This is it?". Apple and Google have shown that significant updates can be made to an operating system on a regular basis, and they've raised the bar of expectation. With 6.5, Microsoft has done the limbo right under that bar...without needing to lean back.
