Resistive touchscreen? Big deal, it works great for most games. Nintendo have a patent on anything that holds open at a 135° angle, blame them. The keyboard is great for what its supposed to do - give you keys that you can use with all the 8-bit emulated machines. Analog sticks = Among the best joysticks I've ever used, bar none. Buttons, tiny? Not for these fat fingers. Heavy and bulky? Hmm .. you got me there, but then again: 12 hours battery life.
Maybe that would be different if Valve got behind the project. As it stands, the Pandora guys haven't done such a bad job for a grass-roots, community-led effort with no funding and all the problems of a hardware manufacturer, starting with nothing, already solved..
