Ok I see your point. You were trying to have him get use of the g3 so yeah thats good advice. If you want to do soemthing really funky you could install Debian on the G3 and run Mac On linux with OSX! Hahha that was the original intention of the MOL project iirc
For sure run morphos on the g4 you will have tons of fun with it and it will be SUPER FAST.
