I was checking the Apple Store today and noticed two different Macbook Air 13" prices and specs. I am not sure which one would suit me best. I am also aware that Apple may come out with a new Macbook Air with Haswell. I am assuming the other specs (flash&memory) will not change therefore I am looking for a suitable investment. Things to take into consideration: -Major: Art History (assumption of main use: essays, ebooks, browsing etc) -Will not use it for gaming -Will not use it for editing (photoshop, final cut/video, etc) -Daily use on my white Macbook (Late 2009): internet browsing (tons of tabs), itunes, Microsoft Office I am not sure which will suit me best, the 8GB or 4GB or the other storage specs. I know it can be customizable but it also costs more $$$.
