I have a 15" PowerBook G4 Titanium with 1GHz processor and 512 MB RAM. I'm a musician, and I use Digital Performer 5.1, Reason 3.0, and Finale 2007 for writing and recording music, and if possible, I'd like to not have to pay for new versions of each of these...It appears that these versions should run fine with an Intel Mac, so I should be ok with that, right? I have an external HD that uses FW400, as well as a USB mouse, all-in-one printer, and then of course the USB cables for my phone and camera...so I need at least 2 USB ports. I want to be able to record with better handling of large-ish numbers of tracks than I am now (that part should be easy), have built-in Airport (although I normally use the built-in ethernet), and burn to CDs and DVDs. I'm not crazy about downsizing from the already-somewhat-small 15" screen I have now, so that's one point against the current MacBook, but am I likely to really need to spend the additional $1000ish for a Pro? I've gone to the Apple Store to get a look at the options in person, and I found that the 13" screen didn't seem like it would be a dealbreaker, but the fact that I use FireWire pretty much constantly (for recording, samples that get played back, and my iTunes library) makes it look like the best options for me are the new white MacBook, or the Pro...but I'm gonna be stretching a bit to even afford a base model white MB.
