Over the course of the past month, I acquired a 60 GB 5400 rpm 2.5" hard drive for my iBook, which I installed a few days ago. Experimenting with my Canon camera's 'Intervalometer' feature (basically, it takes a picture at a set interval, like 1 per minute), I made a short video clip of the process and posted it to YouTube:
The whole process took less than 90 minutes, and I was only missing one screw at the end of the process (that's pretty good when I took out over 50 of the itty-bitty things!). I used instructions from www.ifixit.com (without which I would've been completely lost, and probably ended up with a dead laptop), and am finally able to store my iPhoto library on my iBook's own hard drive.
Not that anyone reading this actually cares... but I thought I'd stick it out there anyway.
