I know that everyone is probably really sick of the Mac questions, but I'm looking for some advice from people with experience with Macs for recording and composing. I have a G3 ibook (which is virtually useless with today's current software) and I'm looking to buy another Mac. The new G5's are out of the question for me because I can't afford to dump a ton of money into a tower along with a nice monitor. This has left me with a few other options. I'm considering a Powerbook. Maybe a 15" or 17". These are extremely pricey but I think it could be worth it. my big concern is buying a G4 Powerbook and Apple releasing a new line of Powerbooks. This happened to me with the G3 but was more my fault than anything. I've heard rumors of dual G4 and G5 Powerbooks, but nothing solid to go on. I know that Apple was having temperature problems with a G5 chip in a Powerbook. ANYWAYS...I just don't know if this would be a good move. I'm also looking at the imac G5. Anybody have any feedback in regards to recording? I know the expandibility is an issue. Lastly, I was even considering a new ibook G4. How well would one of these run Cubase or ProTools? I'm trying to save as much money as possible here...but I've heard so many good things about the Powerbook being a workhorse for audio and figure that it might be worth the investment. I'm not looking to start my own studio as a business here. I'd just like something that's great for audio recordings and visual editing...something I can lay out my ideas on and make a great recording / product. Any advice would be helpful, especially from those of you who've worked on these machines with similar purpose. THANK YOU!!!
