I'm looking to purchase my MacBook Air now that I know what model I want. This is the 8 Gb ram, 256 Gb ssd with the i5. As a digression actually, I'm still not sure if I should go with the i5 or the i7. I've heard the benefits of processing don't outweigh the loss of battery and upped heat and fan noise. Back on topic now: if I go to the apple store right now, will they have that configuration (i5) so that I can start using it today, or will I have to do a BTO shipment online? Admittedly I do not 'need' to have it as soon as possible, I just really want to get my hands on it as soon as possible. For goodness sake I've been without a laptop for three years! Also if you have an suggestions on the i5 or i7 issue, please chime in. If I should get the i7, is that in the stores as well?
