Can't choose between them. I've got a GameCube that I love dearly - mostly for Mario Kart, Zelda, Super Smash Bros Melee and Time Splitters, but there's loads of games I'd never have bought on PC: Prince of Persia (both of them), Need for Speed Underground (both of them

) and so on. These games just work better not only with gamepads, but with TVs. Plus, it's nice to sit on the sofa ever one in a while.
Contarily, I would never for a moment have considered buying Splinter Cell on any console. Time Splitters seems to be an exception to this (it's descended from GoldenEye), but shooting games just don't seem to work on consoles. Half-Life 2 or Doom 3 on X-Box? No thanks, I'll stick with keyboard and mouse (and yes, I know you can get those for consoles, but what's the point?).
