My neighbor has a Tangerine flavored iBook Clamshell. It has a dead battery unit, but 300 Megs of RAM, a 20 gig HD, and 300 MHz processor. It is no longer being used, and they accepted an offer of $120. Is this a great deal? Is this a good Mac for someone who is holding out for an iMac, and will buy a new laptop in 2 years?
