I am extremely happy with my iBook. The extended warranty is very nice, the local Apple store has their own repair facility on the grounds and repairs the machines within 24 hours or replaces them (as long as you buy the warranty). My machine is covered in full for the next three years. If you tweak Mac OSX a bit it is very quick and IMO one of the best OS' I have ever used. I have no problems working with Windows machines from my iBook, you can download and install the ports collection for installing software (or a debian-like package system called Fink). It seems to be the best of both worlds. You get a nice usuable desktop OS with some power under the hood. I pretty much gave up on x86 laptops; they've been nothing but a headache for . As for the tadpoles that specter spoke of, they are awesome if you can find one and afford the damn thing. They are the most insanely overpriced laptops that I have looked into.
