Most of my complaints are related to Windows Mobile, but I also have these complaints about the Touch Pro:
-Screen too small
-D-pad is one of the worst I've ever used
-Volume buttons are too flush with device, not easy to press
-No headphone jack - included adapter is a big bulky joke
-Weather app only works with major cities so it's not accurate for my town
-Youtube links in Opera don't open in Youtube app, try to open in Windows Media Player and fail.
-Pocketable, but still too bulky in my opinion
-Every time you forget to close out of Youtube app it will stop you from being able to start another multimedia app.
-Screen not as responsive to taps as it should be
I've had it for less than 24 hours and so far I'm not thrilled by it.
Windows Mobile:
-Just about everything sucks (except the fact that it's so customizable)
-After 6+ versions of this OS they can't even make a decent battery life indicator
