Ok, just a quick background. My wife's younger sister is into music (she's in a band) and wants a MBP to do her recording etc. I have no experience with Macs in general but from what I understand, music would be more processor intensive. We are debating whether to get her a 13" MBP (non retina) or a MBA. It doesn't seem that she'll be using any graphics intensive programs. She's in college right now so the most she'll probably use it for is for internet, word processing, excel, etc. in addition to her music stuff. I guess my question would be (for you music people out there), what would be the better route to take. Due to budget concerns, we are ruling out the 15" MBP. Does the 13" make sense or should we just save up for the 15" and have her wait a little longer? Thanks in advance for your opinions.
