I don't like the idea. It wasn't until I could run multiple OS's that I considered migrating from Windows to Mac OS. I'm guessing that if they aren't running Intel, then Boot Camp wouldn't be an option. It's nice to have the option. I mainly run OSX, use Windows for certain hardware and programs that are either Windows exclusive, or the Mac version is a watered down port. On occasion, I try to learn Linux, and it's pretty cool to do that with one machine (at the same time). That would certainly put a wrinkle what would normally be an obvious decision, come time to upgrade.
