I use Brazos tweaker, set some aggressive power states, and really lowered the voltage.
I have no idea why AMD threw 1.3v into it, I've got it down to 0.9v stable at 1GHZ.
I can eek about 6 hours video playback on it, it's no where near as good as other tablets, but with the lack of any X86 tablets with clovertrail, I can live with it.
Performance is fine, although some Metro games don't run the best, as they're simply not optimised for X86 low performance CPU's like the C-50. With my PC, since I'm running multitudes higher performance, I can just brute force through it.
I'd definitely say it's worth a buy.
Speakers are the best I've seen of a device of its kind, probably because it's a chunky beast.
It definitely isn't as stylish as other tablets, and it's quite heavy, the display is inconsistent, sometimes (Metro stuff) it's perfectly fine, colours look amazing, but browsing other things can look dull.
Viewing angles are fine, but I see no reason why you'd be looking at it from ridiculous angles anyway
