I've never had an Apple before and i think the new Powerbook 17" seems very nice with all features i need. However i am a bit skeptical about the performance of the G4 1GHz. I have used both Linux and Unix in my work as long as i can't remember as it's my proffession as a sys admin. I am thinking of buying a new IBM Thinkpad T40p as i think it's the best notebook in the world as i have had several ones before. The IBM is simple to upgrade and repair yourself because you can order service parts easily and top notch customer service. With Apple i've noticed you have to ship your machine to a service center and they will fix things, i don't like that as i want my own control of things. So convince me to buy a PB 17" or i buy another IBM. Maybe the Apple way is not my thing at all as i want freedom and freedom i get because i can run all Linux distros and do whatever i want, even repair it myself. I often get the feeling that Apple thinks Apple users are "dumb" and "non-technical people". Is that true? Can someone bring me real performance numbers between a Centrino 1,6GHz and the G4 1GHz? I don't want to buy the Powerbook 17" and then find out that it is slower than my old Pentium 3 800MHz.
