I think I am a lunatic. Let me start by saying I have been a PC user who wants to go to Mac, and I wanted to start it off with a Mac Book Air. I do a lot of home recording. Using Firewire, or Esata external drives to record audio to is typical. Since the Macbook Air has neither I was afraid I was going to have to go with my second choice, a Macbook Pro, because it supports Firewire. Still a very nice machine indeed, but I just really like everything about the Air so much. The look of it, the taste of it! The smell of it, the texture." (Gold Member) Kidding aside, ideally I was taught that recording to an external USB 2.0 drive is typically a bad idea. Theoretically the speed is plenty fast at 480 Mbps. The thing is though, USB likes to operate in shorts bursts of info, not necessarily good for audio, as a steady stream of info is, which Firewire does. I have never done any recording with a USB 2.0 external drive, but after doing some research on the matter, as it turns out it seems to work well for many home recordists. Since the MBA only has USB 2.0 ports, and an SD card slot. No express card, which means no Firewire I purchased a 2011 15" MBP instead, but it turns out I probably could have got away with using a MBA all along. I am wondering if I should return the MBP 15" and get an Air instead. I have been thinking, and flip flopping on this issue waaay to much already, and I am beginning to believe I am a crazy person. Then, I thought I could always sell the 15" when the new MBA comes out with Thunderbolt which would let me connect to a host of different peripherals. The bottom line is, I probably could get away with recording my small audio project needs with an MBA and an external USB 2.0 Drive after all. I hear so many people on hear giving the MBA such praise, and after seeing it in person I can see why, as it IS super nice. The MBP is a better suited laptop for audio work however, I still want the Air more. What to do? Yep, I'm nuts.
