Hi all, I'm coming from a Macbook Pro 2.8ghz Core 2 Duo 2009. I like to do some light photoshop and illustrator. I'm currently studying a Bachelor of Audio Production so I'll be running a bunch of audio programs. I'm also learning coding in my free time. I'm about to pull the trigger on a Macbook Air, though I need some advice on what model to get. Looking at 13 inch. Budget is $1600. Thanks.
