Hello Experts: Long time lurker, finally created an account today to get feedback from experts. I already have a 2008 macbook (black one) that seems to be on its last legs, and was planning to upgrade to rMBP soon. But my high school child's Windows laptop (Lenovo) is getting super slow, and she uses her laptop much more than I use. I have iPad air, and that serves my purpose most of the time. So, being a father with limited resources, I am thinking of upgrading her laptop first and then later I will upgrade mine She is going to use the laptop mainly for school work (word, pp, excel, web browsing, iTunes, email, facebook etc). She is like me in the sense that she hates slow/unresponsive computers with a passion, so I don't want to buy something for her that is going to 'lag' when she opens programs, click things etc., and slow her down. Laptop doesn't need to be portable as she will carry it to school only sometime, but portability is definitely a factor (I think there is not much difference in weight between MBA and rMBP, though processor power seems to be a huge difference between too. I am not a techy person, so just going by 1.3 GHz MBA vs 2.4 GHz rMBP for base models shown on apple site). Will we notice difference in performance between these 2 due to processors? If yes, how much? I am thinking of going with 4GB/128GB configuration. She doesn't need too much storage, but RAM I am not sure. BB has couple of open stock MBAs that with 150 student discount, I can get for 800 or so (4/128 configuration). So, I was wondering if you could help me decide the best Mac for my daughter based on what she will use it most for: MBA because of how light and small they are, or should I get her a Pro? Except screen space, there is no other difference between 11 vs 13 inch MBA, correct? Any help is very appreciated, thanks in advance!
