I have just ordered a new G4 1.33 Ghz ibook. The tech specs page on the Apple site says it uses PC2100 DdR RAM, but I've noticed that most places are selling PC2700 RAM for cheaper than the PC2100. So, my question is, will PC2700 work in this ibook? I'm kind fo confused about this, and Google doesn't turn up anything that answers my question. Can anyone here tell me, please? Thanks!
