Long time gamer. Started in the 80's when I was a wee lad back on a Commodore 64 (it's a very old computer for you young folk).
I primarily game on my PS3. PSN tag is Kalakaua. I have a 360 and Wii, don't play them. Wii is basically used for virtual console and my 360 has been collecting dust since Halo 3. For some reason it just doesn't do it for me.
For all my fellow gamers who are trying to game on the cheap, here's a good deal if you don't mind the older design of the PS3. SonyStyle.com has a good deal on the 80GB PS3. Add the 80GB PS3 and a second DualShock 3 to the shopping cart and you get the DS3 for free. Free shipping too.
