I am wondering how many platforms you game on on a regular basis?
For Me it is:
PC (vast majority of all my gaming likely 85+%)
Gamecube (about 10%)
DS (about 4+%)
XBox 360 (<1%) I was given a 360 as a gift.

I don't own a console anymore, so I only play PC games nowadays.

Up until recently i had about 15 different consoles and computers i used to use but lack of time to commit to them meant i had to sell them off.
I currently use my PC about 90% of the time the other 10% is spent on the Xbox360 & Nintendo DS.
My other faves used to be my 3DO, Amiga 500 & 1200,Sega Dreamcast & Nintendo64.

PC and PS2 for me, can't afford anything else.

used to be just into pc games
then last gen i had xbox and gamecube and kinda stopped on pc games
then i got into gba micro and DS games
now i mostly just play pc games, and haven't bothered getting a "this gen" console.
I've been tempted by a Wii, but never committed.

Pure PC player here.

PC player here. I've considered getting myself a console, for those times my wife wants to play her Sims 2 and I'm bound to watching TV or reading, but I don't know how much life I could still milk out of a PS2 and a Wii has too many games that are kid oriented and not to my liking. I like the idea of doing some exercise with a Wii though but that requires some more crap being bought for it.
I'm better off spending 6 bucks on games and sharing my computer than spending a couple of hundred on a console I'll only use occasionally.

Almost only PC. Scratch that - PC only. I got a Gamecube sitting on some shelves somewhere, but never actually got around to use it much. I actually don't even have an television set, since I do almost all my entertainment on my PC. Except for books, which I still prefer on good old paper. ;)
Edit:
I also got a NES, and a SNES up in the attic, don't know if they still work though.

90% PC
8% Gamecube
2% Nintendo DS

100% PC and proud of it!

PC for the vast majority of my time. Use the PSP on the very rare occasion a good SRPG comes out.

I pretty much have every major console there is.
Lately I've been spending most of my gaming time on my PS3.
360 comes in second.
Barely touch the Wii... same with my DS.
Play My PSP a lot as well.
PC gaming gets thrown in there here and there.. Mostly for GOG and Steam stuff.

PC player since unsuspected times here (286+).... I've got a PSP too in the past years, and I'm planning to buy some new new-gen console in the next months. If I can decide what to buy, given that I dislike the PS3 and almost everything Sony made in the last 3 years....

I've got a PC, PSP, DS, XBox and NES. But most of the time I use my PC.
