The G5 is still an awesome processor for most everyone. I've got a MBP, and I still use my G3 and G4 Macs a lot of the time because they really ARE fast enough for most of my needs. I would probably replace my MBP with a dual or quad G5 if I knew Apple wasn't about to phase them out because I prefer desktops. If I knew the G5 would be supported as long as the Powermac G3 and G4 were, I would do it.
