A friend of mine doesn't know which Air he should by. First of all just let me say that he uses the computer to do web browsing, word processing and maintaining is website. He likes to have a machine that will last long. He (and I completelly agree with him) loves the 11'' screen. I do not know why we even like it more than the 13''. However please help him choose. Here are the alternatives: MBA 11'' , 8 GB RAM, i7 2.0Ghz, 256 GB SSD MBA 13'' , 8 GB RAM , i7 2.0 Ghz , 256 GB SSD The only difference is screen size..... Recomendations ? Thanks !!!!!!!!
