I've been looking at these for about a year now... I can't wait.
but..
the speed is a 533 eden chip. These are pretty good for some things, but not the best for emulation. I'm guessing that it will end up being about the speed of a normal 400mhz board.
but thats still GREAT for a portable gaming.
btw, you can build your own right now for about the same price. The lcds can be bought on ebay for about 100 bucks for cars. And the boards are out there also. So for same amount or a bit more, you can have the size... just not the packaging.
