But only at 800x600 right? Also if you were building one for a PC you'd
want to make it a bit more general so it can be programed to do future
codecs this would also allow the manufacturer to avoid having to pay
license fees on various codecs by not shipping it with the ability to
play anything other than free ones and letting the OS community write
any other stuff they want.
I'm *so* tempted by a GP2X, GP32 or a Pepper Pad, can you plug a USB
keyboard, mouse, thumbdrive into the GP2X and use it as a laptop type
thing? Does your comment mean it has non-free drivers? In a perfect
world I'd like one with Mini-DVI and S/PDIF ports so it could be a
proper (although underpowered) mobile PC.
