Well, one of my friends is debating b/w the iBook and PowerBook. I tried to convince him that the 12" PowerBook 1Ghz G4 is the best buy, much better than the 12" iBook G4. One thing that he said is bad about the PowerBook is the receptiveness of the AirPort. On Amazon.com, ONE reviewer said that the iBook has better reception than the PB. Is this true? What have your experiences been with both? I would think that if this was true, the reviews of the PowerBooks would cover this, but I have yet to see ONE magazine review that mentions it. My friend says that it's because of the metal enclosure of the PB that interferes with the reception of the AirPort. This makes the iBook's plastic enclosure more suitable. is this true?
