Hi there, I currently have a 2015 base MBA and as I'm off to university this September for Computer Science I'm thinking of buying the new 2019 base MBP. I should be fine with the 128GB storage, since right now I'm only using about half of my storage now - but I was reading whether I should upgrade to 16GB RAM as I might end up doing a lot of programming? As a side note - thinking of selling said 2015 base MBA 13 inch. What would you say is the best way of going about this? Through simple sites like music magpie (in the UK) they're offering £310. Is that a good price or could I get more? It's in pretty much perfect condition. Thanks!
