Is anyone else making a similar generation jump? I have an iBook G3 900Mhz, 640MB RAM, 40GB HD. I've just ordered a new MacBook (White, 2GHz 1GB RAM, 80GB HD). I was wondering what kind of speed increase to expect. If they say the MacBook is n times faster than the iBook G4, and the G4 was x times faster than the G3, I'm hopefully going to be very happy with it! Mind you, I'll be happy to have things like USB 2.0 and Airport Extreme that I've been missing out on. My iPod shuffle takes sooooo long to fill up with USB1.
