Looks like it’s worth the upgrade (particularly since I’m still using a 2008 Air, referred to as a “toy computer” in the article, ouch!). The ridiculous audio port overhang issue of the first generation ones is long since solved. But no retina display 😦 And their restlessness with reconfiguring MagSafe is annoying.
Still for $999? Pretty sweet.
Jacqui Cheng’s ArsTechnica review is clear, candid and helpful.
