Just bought a MBA 11", which I'm really enjoying. The portability trade off vs screen size is very workable for me. But I have noticed a slightly different feel to the keyboard on my 2014 Air 11" and my previous MacBook Pro 2009 edition. Am I imagining this or is there a difference? The keys feel a little bit shallower. Or is it just the slanted-ness and thinness of the keyboard section that is making it feel different?
