I personally hated my 500MHz iBook. Sure it looked cool, but it ran hot (burned my legs if I left it on my lap too long), was slow compared to a Pismo (cache), and the keyboard had the BO problem (yuck). That was my first one. I sold it after spraying the keyboard with cologne to hide the smell.

The second one I got for $5 locally that had a "bad hard drive". Turns out the video chip was fried, and the hard drive was fine. At least I got a hard drive and a 512MB module out of the deal. Threw the rest of it on eBay and got $20 for it.
