Hello, I have a few questions. I just got a PowerBook G4 with 512mb ram and a 128mb video card. The rest of the specs are obvious. (15" btw). I found this accessory Guitar Plug at the ThinkDifferentStore.com. It is only $50. My PowerBook came with iLife 05 I guess. I say that because I opened it up and there is just a piano there. I am unsure how to really utilize it for what I want. My questions: iLife 05 pre-installed, do I need to purhcase some add on program which will allow me to record tracks from my electric guitar to the computer? Is the Guitar Plug that I linked up above all I need to do this? If there is more or less that I need I would be open to all feedback. Thanks in advance.
