I'm considering buying the MBAir 13" - I'm a graphic designer and was wondering if it'll be able to handle programs such as Photoshop and InDesign? I'll probably have two of Adobe's programs open at once as well as my web browser, I'm worried that it'll lag the laptop. I'd get the MBP but I bring my laptop with me in between classes and it's pretty heavy. EDIT: just to clarify, I already have a 15" MBP but I had to get it fixed a few weeks back and it hasn't been the same since. It's laggy and I have to restart it a lot, every once in a while it even turns it self off without warning. I thought I'd rather spend more money on a new one rather than getting it fixed again.
