currently have a G3 800Mhz ibook. bought a 12" powerbook (w/100Gb harddrive, more ram) and they just emailed that it will take another week now for it to be shipped. they also said that if you prefer you can cancel the order, and that if supplies change the order may ship sooner. if supplies are low, could this mean a newer revision of the powerbook soon? In your opinion, is it worth cancelling the order and waiting for the next revision powerbook. the ibook is quick, but not always quick (eg. for garageband, powerpoint). I may be able to endure the wait if it's just a few months. But on the other hand, newer versions of the ibook may come out soon, and it would perhaps be a good idea to unload the ibook now. any idea as to when the next revision of the powerbook is released? any advise would be helpful. thanks in advance.
