We just spotted this YouTube video, filmed by Sergey Kuzmin, of the recently announced Sony Ericsson Aspen. The Aspen runs Windows Mobile 6.5.3, a more finger-friendly version of the Microsoft operating system. As we mentioned in an earlier post the Aspen boasts HSDPA (3.5G), Wi-Fi, a full Qwerty keypad and touchscreen, and a 3.5mm headphone jack, among other features.

It looks bigger than we thought it would be but it still looks good and Windows Mobile 6.5.3 seems to run pretty smoothly on it. We'll hopefully have more info for you when we go to MWC in a few weeks.
