I'm currently a PeeCee gamer, but I haven't always been so. I had an Amiga 500 from 1992 - 1997 and it was only the fact that I didn't know whether the Amiga was going to still be around as a gaming platform that made me switch to other formats.
I've owned several machines since my Amiga, including Atari Jaguar, Panasonic 3DO, Playstation, Playstation 2 (crap) and numerous PC's.
My Amiga was most definately the best computer I ever owned though...
