I haven’t bought a console since my trusty Playstation, unless the Game Boy Colour counts.
If I was to buy a new one, which may be entirely possible now I have income of my own (last time a new generation came out I had to rely on my parents, which is never a good thing, and I never got any of them. 
), it’d be the Wii, simply because it’s such great fun to play. That, and my cousin put his Wiimote through their TV.
I wouldn’t mind any of them though, as I could install Linux on the PS3 and play Halo 3 on the 360. You can’t win ‘em all, though.
Vote for which is your favourite right here! If you’re looking from planet.tt-f, I had to remove the poll from the main bit because it was screwing up my XHTML compliance for some reason. Just come to the website and look down the left-hand side. }:)
