Techenical and warranty issues with iBook 14", pls help!

Hi there. I've been using my iBook 14" 1ghz for three moths. Loved it until it started behave badly: keys falling off, the optical drive making strange noises, see no ethernet-port Internet connection, stops installing absolutely Mac-compatible printers halfway through, and what's pissing me off the most is that I cannot change my master password because the system does not seem to recognise the existing password at all. That said, I should also mention that I've been treating my iBook very-very-very carefully as I am Mac-obsessed. I've got manufacturer's limited warranty. I've had it shipped today to the Apple New Zealand for testing. My questions are if anyone experienced same issues in a relatively short use of the iBook, and if my iBook is going to be absolutely technically fabulous after being treated by the technicians or I should request to exchange it for a brandnew one. Thanks.

err, My iBook has been great even though it gets prett roughed up in my bag. I accidentally sucked of my return key with the vacumn, but after a bit of fiddling its went back on fine and hasn't bothered me since.

No problems with mine at all. I've been using it for about three months myself and taken it arround the world once on several trips.

I'd call apple maybe...it shouldn't be falling apart, that's for sure...then again, I treat my powerbook as if it were a newborn baby..for the most part.

Thanks, guys. What about the other (non-keyboard issues)?
