when I bought my MBP I compared the keyboards between the MBP and the 2010 MBA in store. One of the reasons I chose the MBP was the keyboard felt more substantial. It was definitely noticeable. I was a bit surprised to see Anand saying his his 2011 MBA review that the keyboards are pretty much identical (excepting function keys) and always have been. http://www.anandtech.com/show/4528/the-2011-macbook-air-11-13inch-review/6 Was I hallucinating? I definitely noticed a big difference in the quality of the keyboards.
