I'll be getting the htc hd7 when it become available. A lot of people already mentioned the reasons why I would get the phone: xbox live, espn, office suite, sharepoint, the screen size (4.3), real time update on the start menu, 720p video recording, taking pictures and upload them in less then 30seconds, skydrive, integration w/ hotmail & gmail & facebook, contacts linking, etc...
Not many people seem to bring up this item but WP7 & Zune has built in FM radio while the iphone doesn't. I don't always want to listen to the music I have in my library and sometime enjoy streamed OTA.
@CaptainJack: when i got the iphone 3g, there was the 14 days return w/ no questions ask. The thing was that I didn't want to carry around two phones so I canceled my service w/ tmobile (termination fee) and switched over to ATT.
So yeah they give you this 14 days but if you are like me and cancel w/ ATT, well you are screwed and have to tuck your tail and head back to your old provider who will only laugh because they got your $200 termination fee; now you gotta pay again to active, port your number over, etc.
