I am in the same spot... Just bought a base 13" MBA and an early 2011 13" MBP that was on clearance at Best Bizzle... Both cost my $1200 roughly. Most of my work will be done in Eclipse and on a bootcamp partition for Win7 and Visual Studio 2010 for my .NET development... I am torn between the real estate the Air gives me over the MBP, but not entirely sure it is worth the lack of upgradability i get with MBA. Hard Drive really isnt an issue since most of my music will stream from my iMac. For me it was the amount of code I could see at one time on the screen. If you suggest that the upcoming refresh will perhaps at least get to 1366 x 768 minimum, I could be sold on returning each and waiting a couple of months... but how irritated would I be if not much changed...😕
