Looking to buy a laptop. The most I do with my current iMac is record music using logic pro, edit video in iMovie and edit photos in photoshop. I'm planning on travelling for a decent length of time and would like to continue to do this on a laptop. The weight and SSD of the macbook air are really appealing to me. I'm wondering if it will be able to perform the above tasks? I read some reviews of people using photoshop on a 2011 macbook air with no issues, and from what I understand, the cheapest 2012 macbook air 13' is faster then the ultimate macbook air of 2011? So I'm considering purchasing a 2012 MacBook air 13' with the 1.8GHz dual-core Intel Core i5 and upgrading the RAM from 4gb to 8gb. Will this be able to meet my needs? I say I will be editing photos and recording music with it, but I'm still really amateur and I'm sure my needs are also.
