My feelings against all things Windows is based on my years of I.T. experience. The Tilt looks really cool but as it is running Windows Mobile it will be an almost constant nightmare for you if you start installing any apps that didnt come with it.

Windows Mobile is nothing more than a slightly evolved, marginally brain damaged version of Windows 95 (!) and has all the stability issues that come as a free bonus with all things Windows.

One of the favorites with a WinMob device is the weekly reboots that are required in order to facilitate (im)proper operation.

I dont necessarily hate windows- I make my living from it because its pure crap.
