I have 6 around here, but for some reason none has Win7-32 bit on it. Most have xp, a couple have win7-64.
Were I developing for Mach still I probably would have one of each, but since I mostly program for GM or for myself which doesnt require much hardware compatability, it hasnt been an issue for me. I suppose if Darwin is ever put hard to use Ill have to break down and set up yet another machine. Where the heck does one find all the needed space is the issue. :-)
