As I ponder the choice for my first ever MAC, yes the 11" Air is notably more compact and portable, but the 13" is just easier to see for my eyes and not as cramped feeling vertically. That said I'd like to get one in the "Ultimate" version which ever way I jump... In that light the fact that there is only a $50 difference between the two when fully maxed (both i7 1.8, both 4g ram, and both w/256gig SSD) the 13" sure seems like the better deal. It's $1649 vs $1699... Comments?
