In the fallout of the Mac’s shift from PowerPC to Intel-based hardware, X86-compatible versions of OSX floated around the Internets, allowing anyone to install the Apple operating system on a PeeCee (yours truly included). This is one thing Apple does not want, but with both VMware and Parallels working on virtualization of the Mac platform, it’s becoming a very likely reality.
Beyond allowing Windows to run in a window on your Mac, the virtualization camps are coming from the other direction as well: OSX running on your Dell or HP machine. The prospect probably keeps Apple’s brass up at night, but we see virtualization as a mighty juggernaut that won’t be stoppable with hardware changes, so look for some bitter tasting lawsuits or buyouts later this year.
