I think I'll hold out for the 1080p version (crosses fingers, holds breath)
To soon be able to stream/AirPlay one's computer desktop to one's TV is going to be a sweet interaction indeed! This will get around some of the video incompatibilities encountered with the iDevices, such as the iPad.
(My wife likes to watch missed TV show posted on a TV's website, but some networks still post video in the 'archaic' Flash format!).
And no need to convert non-iTunes compatible video formats such as DivX and MKV into the AppleTV readable version - simply mirror directly from the computer.
Great stuff.
Very happy!! ;)
