It's time to get a new mobile computer for my recording company but short of bringing in the Pro Tools LE rig to an apple store and testing it myself, are there any users that run Pro Tools LE on a 1.5GHz G4 Powerbook? If so I'd really like to know how smooth it runs (assuming you use an external HD). What track count can you comfortably make? How smooth is editing? How many plug-ins can you use? How many rewire applications? Etc. Anything would be very helpful! If it helps I would be replacing a P4 3.0Ghz w/ Hyperthreading & 1GB of RAM with a 12" PB 1.5GHz & 1.256GB of RAM. Thanks!
