Which device is best for gaming?

[Kantor]

I would definitely put PC in first place.

• A fantastic and free online service in Steam, which sells practically every game that is released on PC at reasonable prices
• An enormous backlog going back three decades; it's all playable
• The most power, so, naturally, the best performance
• Most games can be played with a gamepad if you so wish, whereas it's a very rare console game that allows you to use KB+M

Naturally, the consoles have their advantages - they are cheaper, easier to set up and play, and have a fair few very high-quality exclusives, but I would choose the PC over any of them.

I'm not going to objectively rank any of the consoles beyond there, because that could get messy very quickly, but I would personally say that PS3 > 360 > Wii only because that's the order in which I like the game libraries of each console. And in general, I prefer consoles to handhelds (limited battery, not enough buttons, and a tiny screen >_< )
