i just did (went with the Hero)
the Touch Pro 2 is an awesome device but not exiting IMO since its basically the same thing i had (and HATED) in a bigger, faster package....
Hero had me with the SenseUI and the fact that HTC indeed re-wrote Androids base apps with their own version rather than add theirs and still have the stock one in the background
glass screen, capacitive, 5mp camera, and digital compass (Layars Argumented Reality WOW!!!! Best friggin app ever made!!!) swayed me to lean towards the hero IMO
its still preference though since people prefer the WM OS as well as the slideout design with a keyboard
