well, HTC HD2 is a really large phone, (but with a large screen too). when im holding it, i always thing that i might drop it.. -no divx and xvid support but not really a big deal for that. -flash on browser seems quite below par. -it has a snap dragon processor. -i can say better audio quality than n900. -very good opera browser, IMHO, -good video playback. that is all i can say, its not even a month when i use an HTC HD2 you can learn more by browsing gsmarena.com just search the phone, and click compare if you are between two phones. EDIT: oh yes! it is unlocked
