Hello. I have an I-mac G4 800MHZ 512RAM that I love but I am thinking of getting a laptop, probably an ibook once they get updated and have Tiger on them, my question is as far as performance goes if I buy a top of the line iBook would that represent enough speed performance to justify the price? Also, does anyone know a place I can sell my iMac at, aside from e-bay. Thanks a lot.
