Anyone know anything about Android Usb Sticks..?

[miseryguts]

Are there any decent ones out there yet..?

I'm considering one primarily for use as a media streamer (XBMC) & perhaps some gaming/emulator shenanigans (if they are capable enough)
Can the latest ones cope well with HD streaming..? I seem to remember reading 6 or so months ago that most were pretty laggy as far as this was concerned.

This has been suggested, is it any good & does anyone know of anything better..?
Also what is the best method of controlling them.. an Air/Mouse keyboard thingy like this or is there a better way..?

Thanks.
