Hi, Wondering if you guys can help me, I've never been a mac user but thinking of joining the resistance. Thinking of purchasing the one below: http://www.apple.com/ie/macbook-air/specs.html The 13" Mac with 128gb SSD (or should I go for 256gb?) I'm wondering, would 4gb be enough for Microsoft office, spotify and webbrowsing at the same time? Perhaps run virtual windows and some programming (programming like visual basic, python, nothing extreme) on it if that's possible I'm not looking to do any gaming (maybe some classic games on an emulator) I need something that'll last me the next 7-8 years and I've been advised that macs are the way to go. Thinking of purchasing this tomorrow but I want the best 1st experience with a mac to be the best as possible! Thanks.
