I am going to buy a 13" MBA ultimate from my local apple store if they have one in stock tomorrow. My question is, if the highest level MBA they have for sale has the i5 and 256gb of memory, should I buy it. I am just wondering if the i7 vs the i5 will make a difference at all. I am going to use the MBA for internet, iphoto, email, youtube, light video editing (imovie for fun), and NO hardcore gaming. So, would I notice any difference?
