I use pro tools on my PC... I am sick of it and am dreaming of the day when I dont receive all their errors. Apparently Mac is the way to go. I am going to college and would like a portable laptop. I need to connect an external drive to record to because i do not want to record to my main drive. I will be satisfied with FW 800 or Esata transfer speeds. My audio interface connects via Firewire 400. The External drive (when I purchase it) will use FW800 or Esata. These Mac Book Pros do not have the specific I/O's that I need. This is very frustrating. Can someone please show me an alternative or fix to this problem?? I would prefer a 15" due to the fact that I will be carrying it around classes. I know the Express Card slot is only available on the 17" so..... If anyone has any adapters or even advice/rumours as to whether the next line of MBP's will have a better, more practical set of I/O's Please let me know.
