How many of you iBook users do NOT use an external monitor with your book? I'm debating whether to go with a 12" or 14" iBook, or possibly 12" powerbook, and would really like to not have to use an external monitor. I'm very much used to 1024x780 on my PC's 17" Flat screen CRT, so the resolution would not be bothersome. Do you guys find the lcd on your book to be good enough for everyday use? Anything you dislike about it (brightness, size, etc)? Would the screen on one of Apple's refurb Albooks (G4 867 12", rev A) be any better or worse? One of these would only run me $100 more than the 12" iBook I priced and is quite tempting..
