The dual-USB iBooks are good all-around machines, and there is very little to fault. Exceptions include the paltry amount of RAM included on some early CD models, and the slow 66MHz system bus on first-generation units. As opposed to PowerBooks, iBooks do not have a PC card slot, S-video out, or an IR port. On the other hand, they (at least the 12" versions) are much smaller and lighter than the PowerBook G4.
