I heard about the Dingoo recently and it looks pretty good, and then there's still the GP32x Wiz I think, that also sounds pretty good. The PSP itself is also a beast, but then I'd have to worry about firmware with it. What about today's pocket PC/smart phones? Which one do you guys think is the best for emulation on the go? Something small of course. I want the best battery life and the best for roms. Does anyone have any suggestions, or know of even better devices for something like this?
