Nokia N900 is better Oh you mean between the other two lol well sony is not known for they updates so picking that and you thinking it took forever for the PR 1.2 than its out of the frying pan into the fire for you with that one. Now on to the htc hd2 nice phone semi powerful if you will but htc cut so many corners on hardware its not even funny. And from what I hear most apps for winmo 6.5 wont be upgradeable to win7 for lack of hardware blah blah blah. So its alot to look at when you jump ship like when I left winmo touch pro 2 for the n900 for htc short coming and hard reboots wasn't cutting it. I saw research both via google,bing or whatever search engine you use and compare specs of all three than wait a month before you make a buy so you sure you will be happy with your new or current phone. Hope this helps
