I got the chance to crack open my iBook today and tinker with it's robot innards. And... the operation was a success! A lot of fun all told.
Now, I have the obligation to pass on a bit of advice to all of you iBook G3 owners out there. If you're having problems with your screen (which you certainly will at some point because of a design flaw), check out this post on Geek Technique. It might save you a few hundred buck since this problem is no longer covered under warranty.
