Which device is best for gaming?

[enrageorange]

I'm not sure what exactly you mean, but I'll assume it means what device is best made to just play games.

for me its DS=360->PC=PS3.

If I buy a ds or 360 game I can just straight up play it the minute I get home. With some ps3 and most PC games I have to install data which is a pain in the butt when I don't have a lot of free time the day I get my game. Now if you mean which has the best game library, well then I think that question has been asked a million times before.
