1. A PowerMac DP 450 w/ 512 ram
A powerbook pismo 500 w/ 640 ram
2. Would upgrade if the Powerbook Ti used more scree resoulution and if the grapics were better and if you could mirror DVD on a bigger monitor. i once tried it and the licence won't permit it. Also i would upgrade if a 1.6 GHZ G5 with ddr memory and two bay doors for a cdrw.
3. i use my pismo for school, and my powermac to do some ocassional projects and to surf the net.
