HDTV, 1080i, 720p, built in over the air HDTV tuner - looks pretty solid. Good choice!
Maybe I'm missing it but I I don't see native 720p support listed. Shouldn't be a problem though- the only thing you will miss out on are 720p games on the original Xbox. 360 and PS3 will upconvert 720p native sources to 1080i.
Sony make excellent TVs and I'm sure you'll be happy with it.
