Next gen consoles! The Revolution is the sleekest looking of all of them (and smallest), and promises compatibility with not just Gamecube games, but N64, SNES, NES, etc via rom downloads on a Nintendo site.
Xbox 360 is by far the most powerful (something like 1 terraflop of computing power), but also the largest, and well, most computer-like.
And you have the PS3 right in the middle power-wise, and probably least creativity-wise (PS1, PS2, PS3... come on).
They all have wireless controllers, wireless internet connectivity, and all around awesomeness.
I'm buying Nintendo, and possibly Microsoft (for Perfect Dark sequel and Halo games).
