If anyone needs VirtualPC for a Windows-only app, as I do, MS will release Version 7 any day now--and it WILL run on, and claims to be built specially for, the G5 chip. Earlier versions would not run on the G5. Not cheap, of course. List $99 for an upgrade; I found the best deal at Buy.com for $76.35 and preordered it. Full version with XP Pro or 2000 Pro lists at $249. A great feature, with Panther, is no need to download Windows printer drivers--they claim clicking Print will use the existing Mac printer functionality. Soon, I can move that one app off my wife's G4 iMac and onto my Dual 2 G5! Steve in Raleigh
