I would love some feedback from some smart macrumors folks I'm comparing a 13" Air with 1.7 processor for $1599 with 256 SSD included vs. 13" Pro with 2.4 processor for $1199+$400 256gb SSD upgrade (install myself) So my question is, why would I not just upgrade the Pro and come out at the same price with a more beefier processor? Maybe for the slim body of the Air, but I can handle a little thicker case if it means I get a better machine. I guess the big question is how big of a difference is there b/w the two processor speeds? And finally with the recent silent upgrade of the pros, do you think it will force apple to upgrade the airs? Perhaps if they did then this wouldn't be an issue.
