hi guys, i finally found a buyer for my 15 mbp, so ill be getting the new mba.. i have a few days to decide 11 or 13 lol... but a few quick questions, since i have to sell my computer before i get the new one, how do i transfer everything? whats the best way. im thinking using an external drive back up using time machine, then just plug it into the new machine? will this transfer my apps too? thanks for any answers. also feel free to suggest a comment on 13 vs 11, i dont do much but word, excel, youtube, online hw, itunes etc.
