Let me see...
Wii (duh), XBox 360, (Iused to have a regular XBox, but it broke), NES 64, DS (the regular one, not a DSi, or lite), SNES (it's at my grandparents house, does that count?), and a PC (obviously).
Does a Wii count for Gamecube, because you can play Gamecube games on the Wii? If so, than I also play the Gamecube.
