I bought my Wii on launch because I've always loved Nintendo!
I do use my xbox the most though of all my consoles! I literally bought it so I could play Oblivion! XD I'm not wealthy enough to be able to afford a gaming rig and I really wanted to play it at the time, so when I had the money to, I just got one and got oblivion. ^o^ Would've got a PS3, but was just too expensive at the time and i don't think Oblivion was on PS3 then. lol
I did eventually get a PS3, but mainly for the exclusive titles and because I was looking at a getting a blu-ray player to go with my new telly last year!

The only PS3 I ever wanted was a phat 60GB, so I could retire my PS2 as well. IMO the only PS3 worth getting is the phat 60Gb unless you buy SE consoles.
