I would like to pick the knowledge base on the Forum? I can read articles all day long on this and never get the true answers I hope to get here?

Teach me a little about the GPUs in the Android level devices? I have seen Adreno, Mali, Nvidia, are these all good GPU's or there any to stay clear of for gaming? I also noticed that ATI Radeon GPU's in most of the major gaming consoles ? Do they not make a mobile GPU and is it any good?

To me Ouya will have a hard time with NVidia Pricing how do you get the latest technology and keep a unit at $100.00 or less? NVidia has never been cheap and write fully so!
