Hi, I am looking to buy my first Mac. I'll mainly be using it for recording and writing music (probably Logic Express or Studio). I was going to get the 15" MBP with the 2.66 Processor. This should be plenty powerful to run my music applications, even with lots of tracks, right? One question I have is about the hard drive... how much better would the 7200rpm be? I will probably end up writing to an external HD via the FW 800 port, so I'm guessing it is not that important. Still, if the extra 60$ makes a big difference, I would be willing to spend it. I was also going to use a USB hub, since I'll use more USB equipment than there are ports (2). Will using the hub degrade the performance of anything like a USB MIDI Keyboard and external soundcard? Anything else I should be aware of regarding potential weaknesses the new MBP has vs. the older models? I'm aware of the FW 400 port drop and glossy screen only, but these do not concern me too much. Thanks for reading.
