I have the base macbook air but with 128 GB, and while I am pretty happy with its performance, my daughter is in love with it. I am tempted to give it to her, but one of her favorite programs is Garageband. I don't know how to use Garageband, so I can't test it. So I'm curious to know if anyone else with the 2GB RAM and the 1.4 GHz macbook air uses garageband, and how they would rate the performance. Thanks in advance.
