I got my Air a week ago and it's great. I haven't had any bad/slow experiences with it so far, but I am still wondering if I should have gone with the 8GB one to make it more future proof as well as not risking suddenly getting something I cannot run smoothly enough. I don't really do any coding or video editing on it, so in general I don't think I do much memory intensive stuff. But I'm still not a fan of delays, not being able to run videos in full HD and such.. So I am considering if I should try and see if Apple will take it back for an 8GB one.. What do you guys think?
