I ordered a gently used iBook online and a few other items to upgrade it once it arrived. I ordered a superdrive, extra ram, and a faster - larger hard drive. I've been reading all over the place that the iBook G4 is a bear to work on so I had high expectations. I was considering paying for the install but the Apple Genius route was going to cost me well over $100 for all of these items. One place actually equated working on the late model iBooks to performing brain surgery on yourself. That's a bit of overkill. I received the upgrades in the mail at various times last week and the iBook arrived yesterday afternoon. First, I booted it up to make sure it came in good working condition. I followed some advise I read on a number of sites and decided to take my time and just dive in. About two hours later I was nearly finished. I was gentle with the plastic exterior and took care to remember where all the screws came from. Once it was all closed up again (no screws left over) I powered it up. I inserted the original software that came with it in order to load OSX and it worked like a charm. It really wasn't so bad. It was challenging but that's part of the fun with this sort of thing. I'm typing on it right now and it works like a dream. This is my first Mac experience and I love it! For those of you not concerned with voiding the warranty or whose warranty has already expired I say go for it if you have a bit of confidence with electronics. For those of you who are scared but feel as if you can do it ... I'm in law school, not technical school. If I can do it many of you can too. Good luck with your own projects. I'd like to hear some similar experiences if you would like to share.
