I was under the impression that the revision B 15" powerbook had a 1.33 ghz G4...in any case that is what the computer in question has. I think the pbook is the better machine, and yes it is a horrible deal...you can thank my father for that. He had purchased a 17" powerbook from ebay for 1600, it was nice until it froze up and wouldn't recognize some of the hardware, we returned it and now he decides to purchase the 15". I was trying to convince him to purchase a new ibook from the apple store, but it's kinda too late now...originally I was questioning the differences between the two, but am quite aware of them now. Now I'm looking at procedures for modding the pbook.
p.s. I don't care to hear about how we just got screwed on the price, I am well aware of this...Hell, I was just talking to someone who wanted to sell me a new 15" pbook for $1350
It has already been purchased for $1500 USD.
