PS3 slim white, SSD, full digital, with DualShock 4.
Less noisy than my PS3 FAT 60GB.

I still play with my brother's SNES. So I could do that forever.
But I can play these games and others also with the Wii Us VC but that somehow feels like cheating for this thread...

Easy: Wii. All Wii + GC Games AND N64 VC + some cool wiiware games? Unbeatable. (For me at least)

PC master race! If you don't count it you clearly agree that PC is better than anything else! ;)

Definitely ps3. I could see myself gaming on that machine alone if it was the only console that I would be able to play. I still have some gaming session with my ps3 from time to time.

It's hard to say at this point. As it stands, if Nintendo gets their act together with the virtual console, Wii U could become the best console to have, featuring stuff from NES to Gamecube, and the occasional game from third party consoles, and Wii backwards compatibility. If they don't do it with the Wii U, Nintendo's fusion console could bring together every Nintendo console under the virtual console. For the rest, there's PC emulators. You can't emulate a gamepad or a wii mote on the PC too easily, whereas you can pretty easily emulate Playstation games and Xbox games. The Kinect is PC compatible too, isn't it? So you wouldn't even have to sacrifice those games. Nintendo and PC, it's all you need.

PS4 for sure.
I'm thinking future hear. I know PS4 will get all multiplats plus JRPGs in the future.

I'd choose the PSP since it has awesome games, plays ps1, N64, Nes and snes games and has tons of homebrew support porting many mobile game.

N64

360 because I'm a fanboy.
