I've gotten used to my raspberry pi's power draw of 3.3W for idle :p

While ARM is much nicer on many fronts, opensource video decoding isn't 
one of them (YET, I  am involved with linux-sunxi where that might be a 
reality sooner rather then later).

It would serve two functions, Mediaplayback, and the occasional 
(emulated) game. While I agree, they aren't very memory bandwith greedy, 
3D GPU stuffs might want faster memory then.
