Ooh a real reply! Thanks.

Yeah, as I said, the machine is pretty much immaculate except for the sticky keyboard incident, and I've already replaced keyboards on friends' iBooks so I could do it in about five seconds. It's just too slow for the sorts of things I want to do with it now, but would be great for a high school student or even college student just wanting basic word processing and web browsing capabilities.
Also, I discovered a while back that THE best cleaning product for white iBooks is a little square of a
Mr. Clean Magic Eraser. It is the only thing I have ever found that gets off those ingrained black smudges you get where your hands rest below the keyboard. Scrubbed up properly, I bet my machine could look close to new (except the minor monitor-peeling-away-from-the-hinge issue which seems to be what happens to all iBooks eventually).
I was considering selling it over here in NZ just because Apple products are HUGELY expensive and I thought I might get a bit more money for it, but I would probably get more bids on Ebay than on TradeMe (the Kiwi version of Ebay) so I'll probably just wait until I get back to the States.
Thanks for the advice.
