Hi, new here, hoping to get an honest informed opinion on something. I plan on getting a 13" Macbook Air very soon, however have a bit of a budget. I will mainly be using this for basic iOS app/game development, along with basic use of pages for any essays or projects needed in class, and possibly some audio editing, but nothing too intense. When I order my Macbook, I am definitely getting the upgrade from 4Gb to 8Gb of RAM. My question is, what would be more important to add to this; upgrading the flash storage from 128Gb to 256Gb, or upgrading the i5 processor to an i7 and possibly buying an external hard drive in the future if storage becomes an issue? Any opinions or insights would be much appreciated.
