With the update and subsequent price drop on Best Buy's website of the 2013 MBA 13" my interest has been piqued on buying the base model $899 machine with 4gb ram/128gb hd. I have a 10% coupon which for me, after tax price will run around $875.00. I'm not eligible for the $150 student discount with Best Buy. So my situation is that I already have a pretty kick ass, for me desktop replacement rMBP 15" that is humming along as my primary use computer. I have no issues taking this computer on the road as I travel at least once a month for a week at a time. For those that own a MBA, is it going to be too jarring for me to "downgrade" to a MBA for my travel? I guess even for $875, I'm mainly concerned about still choosing to just travel with my rMBP and possibly just regretting the MBA in the future. Edit: I guess to address why I'm interested, it is the entry level pricing and the fact that the Air is for the most part, fully featured laptop that is a worthy travel companion due to its size and weight.
