In regards to the air/mini, I'm not convinced they have no place as you're describing it. My 2012 MacBook Air handles stuff just fine with modern browsers and modern applications. The numbers and specs are fine for a computer that "just works". A webpage has never been the culprit to make the thing sweat (excepting bugs with flash/Java plugins). They probably could afford to bump the specs easily if they wanted to run a new line, but to suggest the user experience is bad on these machines just based on numbers is incongruent with the reality of said devices.
