howdy all, Ok, My friend bought a new G4 iBook and it is really nice, fast and QUIET! The FAN has YET to come on, not even during a DVD! Heat is NOT even an issue. It is really sweet and I long for one despite that fact that I have HOT AND LOUD Powerbook. I long for a quiet, cool<not hot, lap buring> computer to work on, in peace and splendor. I value cool, quiet while I work! Now this has been a real trial for me to find a unit that can fit into my perceptions of these qualities. But my friend got the 933 model and its is just splendid, and I can see myself happy with it for a long time to come. Now here is my dilemna. First, I hesitate at getting the faster 1 giger cause the CPU might be overclocked and this could cause the fans to come on. Of course 933 is not that much less, so it is of little consequence. My next thought is the 45 dollar upgrade to a 60 gig HD. Does anyone know what the makers are of both HD's and if there are any differences in noise etc? If there is anyone out there with any of these models and could share their experiences, I would be very VERY grateful! TIA all oh yea, anyone out there use a 1 gig ram chip in their new iBooks, I would love to hear that these work!
