Does anybody have experience with Lightroom 4 and CS5 or CS6 with the new top BTO 13-inch air? If so, how is it? I'm thinking of getting the 2.0/8/512 and canceling my rMBP order. I am currently using a 15-inch late 2011 MBP. I haven't been happy with it because it's slow when I do any photo editing. I believe this to be because of the 7200 rpm HDD. (I believe) I can't swap it out for a solid state without voiding the warranty, which would be nice to keep for sales purposes. Thanks for any help/opinions.
