FWIW, if you have been quoted $300 to replace the iBook's hard drive, you should look elsewhere or look into doing it yourself. A little time spent on your part can save you at least half that amount. I don't know about the newer iBooks, but older Mac laptops were very easy to get into.

I recently bought a 120 GB hard drive to upgrade my Pismo for a mere $90. So $300 is way too much...

Peace,
