It's good that Apple is in the refinement stage now. Even though they are extra conservative on display size, the one constant is refinement. There's a lot to be said for continuing to improve a little at a time.
In the beginning there were opportunities for exciting big improvements, but as with any other product, there comes a time when it reaches maturity and the gains are smaller. There's nothing wrong with that.
There's nothing wrong with not being excited either, it proves that the platform is doing what it's supposed to do. And as other posters have said, we can buy Android for the modern sized spacious displays they offer.
I must have more than one MBP or MBA to do all the things I want to do under the various conditions when traveling working in a lab or office where portability is not important.
So in my case I have enjoyed and preferred to have two lines and two phones as my regular daily carry. It's fun, it's a way to enjoy variety, and it's a great way to have it all. There is no perfect phone or laptop anyway.
