Hi Chris, > G4/800, 640 RAM, Combo drive, Airport, 40GB HD > G4/1Ghz 1 GB RAM Superdrive, Airport, 60GB HD - Logitech optical wheel > mouse I use with either one Interesting - I am currently using an 800mhz tibook and have just ordered the 1ghz model. Can you tell me if you've noticed much difference between the two? (graphics or cpu speed, etc?) regards, Mark
