I'm just irritated because I had the lemony G3 model which had repeated logic board failures. Apple always got the machine back to me within a couple days (pick up day 1, fix day2, back the third or fourth day). The G4 is the machine Apple issued to replace the G3 after the fifth or sixth logic board replacement. I'm really irritated that the replacement machine lasted just a bit over a year. And we do have Applecare, which is great since an extended warranty program hasn't been announced for the lemony g4 series. Ah, well, maybe I'll get an even newer machine after the next few logic boards fail.
