Eagerly awaiting the store to be back online, and as soon as it was live I went to look at the spec bumps on the Air - Retina MBP is just too expensive and I don't need it. Anyway, for £100 more I can get an i7 or for £60 I can get 8GB of RAM but I can't really afford both. Which is the more worthwhile? I'm not going to be using it for anything intensive either CPU wise or RAM wise to be honest, basically just going to be used for day to day stuff, a bit of Photoshop and web design. Any thoughts on which I should bump up?
