Long story short. I am without a computer and this will be my first Mac. I have been waiting patiently for Haswell rMBP since like march/april and need a computer for school and other reasons. I think the Haswell Air is sufficient for me but I really hate the idea of buying this and then the product I actually wanted all along releases. So, I would like to purchase the Mac notebook that will retain its value the best until about October and then I will liekly sell if the loss is not too much. So, Which notebook would it be 11 in MBA or 13 in MBA or something else? And How much of a loss can I expect after back to school promo and education pricing? $200? $250? $300? Please let me know I would like to be make my decision before I leave for vacation shortly.
