I am thinking of getting the new HTC touch pro which uses Windows mobile 6.1. Have been doing a lot of research on it and one of the pro and cons is windows mobile. My question is, if WM ever gets an upgrade (WM 7.0?) in the future, can I upgrade this phone? Not sure how updates work in the mobile world, are you stuck with what you got when you bought the phone.

On a different OS but similar note, if Androids UI ever really takes off would it be possible to install that OS on the phone as well?
