Apple iBook 600-MHz PowerPC G3, 128 MB, 15 GB

When Apple set out to create the iBook, one of key design goals was to create a lightweight notebook computer tough enough to stand up to the occasional bumps and other unexpected mishaps of life on the go. From the standpoint of a laptop, the inside of a backpack can be a fairly inhospitable place. And yet you shouldn't have to walk softly just because you're carrying the most appealing notebook ever.So Apple made the iBook's sleek case out of impact-resistant polycarbonate plastic. That would ordinarily be sufficient to survive the rigorous of everyday use and abuse, but Apple didn't stop there. Inside, a sturdy magnesium frame provides superior strength, while reducing the iBook's weight to well below that of other full-featured PC notebooks. Apple even rubber-mounted the hard disk drive for added bump tolerance, so you can store all of your digital goodies on your iBook and still enjoy peace of mind. Additionally, the iBook has no I/O doors, protruding latches or levers to break or snap off when tucking it into a backpack or briefcase.
