I've had my 500mhz G4 Titanium Powerbook for about 3-4 years. I will not trade it for anything in the world. It goes EVERYWHERE with me, it's taken a beating, and it keeps going, and is honestly faster than my 1.8 ghz P4 running XP Pro. I will upgrade to a G5 Powerbook when they come out, but even then, I doubt there is anything out there that my G4 can't handle. I love it. If you want to get a BIG discount on anything Apple, let me know, and I can hook you up, but only if you're a student.
