I've decided to spend more time "researching" for the updates I'm going to do when I finally get an iBook. My questions is, does this hard drive fit in an iBook? Fujitsu 80GB 2.5" 5400rpm 8MB cache It's AU$197 which is cheaper than Apple offer for a 80GB 4200rpm upgrade at the moment. I understand that I'll have to pay for installation but I'm just curious to know if it will work. Anyone able to help?
