I also considered waiting for the Air to be refreshed, you know.. to get the latest and greatest, but then we're probably talking after the summer, and... that's quite a long wait when I could really use one now. And if, for some reason, it turns out I could really benefit from a faster CPU I'll consider selling this one in the fall or whenever the new Air does come out, and upgrade to the new one then.
Btw, I linked to this review earlier on this forum, which really got me convinced of how capable the current MBA is: Frank Chimero - The Setup.
as mentioned here earlier ...there wont be a refresh for MBA by another 6-8 months .. i think you did the right this ENJOY !!!
