ZERO STARS. MICROSOFT ONCE AGAIN PROVES THEY ARE INEPT AND LAME. After a fair amount of research and thinking finally I wouldn't need to worry about compatibility issues (after all, I was going PC) I open the box (read: restocking fee) and install the software only to get this friendly Bill Gates message "Virtual PC doesn't work with your machine." That's right. It sure doesn't. In System Requirements admittedly it says for any G3 or G4 Mac and I wasn't thinking "Oh that means not a G5" but it should CLEARLY STATE NOT FOR G5. After all it goes into a whole bunch of mumbo jumbo about adaptability with Jaguar OSX. So what does work with the G5? After being guided to Mactopia and after a bit of digging around it says "Virtual PC for Mac G5 --stay tuned we're working on it." Yeah, I keep my eyes glued. Just another reason I'm glad I own a Mac.
