I've been using PearPC for some time now, in the beginning for lack of an Apple Computer, currently for testing web sites on multiple platforms. Could be faster, but not bad at all. I suppose my PC is getting a little old as well...

Also comes in very handy in tech support situations. I recently had a client inquire as to how to get a email account setup on his Mac. No idea. Fire up PearPC and work it out. Done.

If I had more Hard Drive space I'd setup two or three different configurations. I currently only have an OsX 10.3 install, but a 10.2 and 10.4 would also be nice or over the top :)

More soon to follow...
