I am tired of pc / laptops dying and breaking. I have a y500 that is a montser but it just died on me, and im tired of new pcs lol. Long story short. Ive been seeing deals here and there, I saw one at best buy 799 macbook air 4gb 128gb. 13 inch, with movers coupon etc.. 700 or so. Will there be better deals? any features you can think on waiting for? Should I get a 4gb? my current is 256gb OS msata/16gb ram/1tb memory storage. None of which I use, I just browse, check emails, facebook, forums, listen to music. I am going to be keeping old laptop just to torrent /store things. So I am wanting a macbook for everything else. Is 4gb future proof on macbooks airs? how much OS takes up from the 128gb ? Reliability for years?
