You can now run Windows XP on Macs, equipped with the Intel Processor. I'm sure that will be a boon to those who want to run non-mac software (the 90% of software you can't now). You can also now make the switch of operating systems permanent (isn't that what every mac owner wants? LOL!) http://www.cnn.com/2006/TECH/ptech/04/05/apple.software.ap/index.html
It's a wonder the apple/macs have stayed around as long as they have, without some added compatibility. Maybe this will add life to the format.
I've heard the opposite that they run well. I thought about doing it then stoped and asked"why?" I went back to doing other things.
Last year they promised me they would not allow a Windows on new Intel-base Macs. Now we have XP on Mac and Tiger on PC. Oops!
