Hi. I'm looking to purchase a MBA and I would like to get the most bang for my (thousand) buck(s). I'm going to be doing lots of web development, internet browsing, Skyping, as well as using Photoshop, Illustrator, and InDesign. I plan on using this at school frequently, as well as on-the-go and sometimes at home. I already have a 1tb external hard drive. I was considering the new stock 13" MBA with 8gb of RAM for ~$1200. I like this because I hate charging things and it obviously has a decent performance boost. However for $1000 I am able to get a used (like-new) 13" MBA from 2012 with 8gb of RAM on ebay. It even comes with the box. These options are about the same from what I can tell. Obviously the newer one will be slightly more pristine. It will also have 5 hours longer advertised battery life and better performance. However, not ever owning a laptop (or a MacBook), I don't know if those benefits are worth the extra $200 price tag, so I'm looking for advice.
