The 12" ibook is a lot in a little case, but for the same $ (or less if comparing to 14" ibook) you can cobble together a faster machine with better video and superdrive, 15" monitor, wireless keyboard/mouse. You give up a battery and all-in-one design. If you only need limited portability--to move around the house and transport to other places occasionally (no classes, coffee houses or airplane use)--is the "new" mini w/ 1.5, 64, and 5400 drive a much better buy than either of the ibooks?
