Hey guys so I decided on getting a MBA for school use. I'm definitely getting a 13" since 11" just seems too small. Battery life is a huge issue, but I don't mind carrying my charger along with me since MBA 2013 is expensive. I got a good deal on a refurbished 13" MBA for $849. Should I hop on that deal and buy it right away? My MBA would be for only basic use so I don't need anything high end. I'd like to get the MBA 2013 but do you think I should pay the extra $300 for it? I mean the only thing I see is the battery life being useful. Let me know guys! Also, I might use the MBA 2012 in clamshell mode when I'm home sometimes!
