XP on a new Imac
For what it's worth, I am currently running ps2 windows on my mac using fusion and I have no problems. I did upgrade to 3 gb memory. I am not a "power user", but I have had no problems at all and it seems to behave similar to when I ran it on a windows machine. Fusion allows you to run in a full screen mode that looks and feels just like windows. Also, the newest MAC OS comes with boot camp which allows you to boot the mac as a windows machine (without the MAC os even running). You need to own a copy of Windows, but that solution works extremely well.
Once you've used a MAC, it's hard to go back. It's a much better machine in my opinion.
Someday, I'll think of something pithy to say........
