Amongst my friends, there are:
11 Wiis.
3 360s.
14 DSs.
1 PSP.
0 PS3s (though one of my friends bought one at launch, but unfortunately the prices were sucking on ebay...I think he ended up selling it for retail value + shipping)
Most of us play on the PC as well.

Bet with disolitude: Left4Dead will have a higher Metacritic rating than Project Origin, 3 months after the second game's release. (hasn't been 3 months but it looks like I won :-p )
