Man, this takes me down memory lane:

Now sitting gathering dust in my parent's store room:
1x Atari 2600 (Damn old wei... Checked it a couple of years ago, and still working, tho the controllers are almost crapped out now)
1x NES (Gathering dust in the same store room...)
1x SNES
1x PS1

Passed on my brother:
2x PS2 Slim (Black)

Using right now in my apartment:
1x Wii
2x Xbox (More for XBMCs now)
2x Xbox 360 Elite
2x PS3 (1x 60GB/1x 40GB - Both Black)
3x PSP Phat! (Though one is with my collegue, though I'm planning to let him keep it as a b'day present)
