Hi all: I am owner of a refurb. Rev.A MBA, and i am very happy with it. Also i have a Macbook, but i use it mostly like "desktop" computer, because since i bought the MBA i do not want to carry more weigth than this one. Now, i am thinking to buy a refurb. Rev.B MBA, and give the Rev.A to my girlfriend, who only use it for email, internet and office works. So, i think that it would be a good idea to buy the top one (1.86, SDD), because the difference between this one and the lower rev.B (1.6, HDD) is 500 (nearly 376$). The point is : do you think that for a dairly use of not very hard works (for intensive photo or video edit i use the Alu Macbook) is it interesting to pay this difference of money? Please, let me know your comments, because i know that mostly of you could help me with your knowledge. P.D. : excuse me if my english is not very good. I am spanish and i do my best.
