Im split on which MBA should I purchase? What is really the difference between 13 and 11 inch Macbook Air? Besides the obvious one, screen size of course.... Not sure if true or not but I read somewhere that 13 inch is faster than 11 inch... I don't understand how this possibly could be true since both come with the same processors. Also is Thunderbolt 1.0 even worth it on MBA 13inch? Or is it something so outdated that I might as well save $$ and stick with 11 inch?
