I'm thinking about selling my ibook G4 and using the money towards buying a Macbook for the upcoming school year. I have no clue where my operating cd is, and I'm nervous about selling my ibook w/o wiping it clean, since I've had credit card info and other stuff on my mac. Does anyone know how I can wipe it clean to sell? Also (sorry for the long thread post), how much do used ibook G4's go for? I bought my ibook in October 2005, its in good shape except for missing the bottom footpads and one of the pads on the upper left screen. Does anyone have experience with this....is it better to sell on ebay, craigslist, or what site would y'all recommend? *ooops, just realized the spelling mistake in the title. Sorry about that ** And I just also realized I should've stated the specs for my ibook G4. It's a 12" ibook Mac OSX 10.4.11, 1.33 GHz PowerPC G4, 1.5 GB DDR SDRAM (I added 1gb ram).
