Ok guys I need your help. I have been ready to switch to a Mac for over a year and I am prepared to take the plunge. However I am really torn between the 15" Powerbook and the 17" Powerbook. I have to travel every other week via plane so I need something that will travel well. This will be my main computer and I will not be buying a monitor. I stood in the Apple store for an hour trying to decide which system I should buy. I have read and seen first hand some of the production problems with the 15" PB and I am sure those glitches will be solved very soon. I am of course waiting until next week to buy the system as I am hopeful we will see an update or a price break. Hell I would take both. Is the 17" worth the additional $400?
