Btw, you can get cheap atom mother board with Nvidia G9400 embedded, for 250 USD (mobo only) it should give you enough horsepower for full HD. And Nvidia has a product that features ARM and a graphics processor. Not sure if they will release binary driver for ARM tho. If it does, Chrome OS might be worth looking into. I'm not sure what are you looking for, are you looking at media acceleration or some number crunching stuffs? Cheers, Kim Yong -- There's no place like ~
