Do not buy a new mac now. There is a new version coming up with the retina display. Might just be annouced with the new baby Ipad announcement. Of course if you want to same some money, head over to Microcenter if you have it in your area, they have it cheaper there for 100 less or even more. Here are the examples, this is from Cambridge Microcenter in MA http://microcenter.com/search/search_results.aspx?N=4294964325+517+4294966363 .Pro is more powerful, but Air is thin and light. Decide if you want form over function.
