The NY Times had an article today about Parallels Workstation, a beta software that allows you to run OS X and Windows (any version, not just XP) simultaneously on an intel-powered Mac. You don't have to reboot when you switch. You can copy/paste between systems. You have to "network" them to share files. The free download is available at http://www.parallels.com/.
This sounds like the most acceptable solution for the "I don't wanna buy a PC just to run FrameMaker" folks (of which I am one, although I already have both a Mac and a PC). Pat Christenson
