Very torn here between getting a UK MBA 8GB for £930 or a USA MBA 4GB for £500. Am I crazy to pass up the saving? I'm currently using a 2009 white Macbook with 4GB, and it constantly pinballs and I have to be careful of memory usage (I run flashblock, adblock etc) I was planning to buy a 2014 MBA with 8GB ram and 128gb SSD later this summer. I may be able to get the UK edu discount, so it will be £800 (inc free 3 year Applecare) which is about $1,350 in US dollars. A lot of money for me and I'm not fully sure if I can stretch to it. (Without the edu discount, the MBA 8GB is £930 ($1500)) However, a USA friend may come over to see me this summer. She's offered to bring over a MBA for me. With the Best Buy student discount currently on up till July 12th, she can get a MBA 4GB for $800 or £500. That's nearly half the price of the UK model, but with 4GB of RAM instead of 8GB. Can I manage with 4GB? Can you advise if you think I'm in danger of spending £500 to just have the same memory problems as I do with my current 2009 white Macbook? My usage is mainly research and planning, with several dozen website tabs open, evernote, reminders, ical, MS office, Google Docs, lightweight video editing, iPhotos, organising and co-ordinating groups through Facebook and so on. My 4GB whitebook can't manage to do all this at the same time. I'm sure a new MBA with 8GB would be fine, but can it do it on 4GB?
