Welcome aboard Bob, hollar if you have an questions you can't figure out - I've been an Apple guy since using my first one running lights for Kenny Loggins in 1990 - I also worked for Apple for over 8 yrs.
I just got my 12" G4 PB back from service (bad modem) and it only took 3 days - they send you a custom box over nite, drop the copmuter in and hand back to the courier and it's back to you in no time! Waaaay too slick a process....
