On my intel based MacBookPro I run a program called Parallels. It allows me to run the mac OS and Windows XP at the same time. I understand that I can lso run Linux if I want but since I have no use for it I’ve never looked into it. I a few pieces of software that require XP to run otherwise I’d never would’ve worried about it.
Ditto to all of the above on my Mini. i haven't run across anything Windows-only for a while; all I use Parallels for is checking Web pages in Windows browsers.
