Currently, I have a Dell desktop with a 1.7 gHz Pentium 4 and 256 MB of RAM. It does a decent job, but I would love to have something portable. Aside from the usual word processing/internet browsing stuff, I will be doing some audio editing. I use Reason and have an Oxygen 8 MIDI controller for softsynth applications, and would probably end up just using GarageBand for audio recording until I got the money for something nicer, like Logic. I plan on getting a simple USB audio interface such as the Tascam US-122 for recording (since I would only be recording myself; I don't really need anything with a crazy amount of inputs) and getting a firewire enclosure for my 120GB 7200RPM hard drive. Most stuff I record probably won't use more than 5 or 6 tracks going at once, so with a RAM upgrade, will the iBook's processor be able to handle it allright? I was looking at the Powerbooks too, but is it really that much better than the iBook to justify spending that much more money? Also, I'm currently a college student and will be using the edu discont. Does anyone else use an iBook for audio, and if so, how well does it work?
