Hi I have seen a number of MBA 1.6 with HDD and the 9C90 screen and several MBA 1.86 SSD with the 9C9A. However not the other way around. So I am curious does only the 1.6 come with 9C90 and only 1.86 with the 9C9A? This is for Rev B only! Hence my poll. Thanks P.S. I have seen this pattern at an Apple store, 2 Best Buys and Micro Center following this pattern plus one at Starbucks. So I am starting to think it is more than a coincidence.
