I bought a Titanium powerbook G4 first, with Final Cut, with 500mhz, then I liked it so much I got a quicksilver G4 with dual 1000s. In some ways especially on the internet (i use the same base station airport system for both) the powerbook seems ifaster. Certainly the OS is not as caprious as X. I also bought the system upgrade to 10 for my powerbook but have thot better of applying it yet..
