The list of Kaby Lake laptops of all sizes is starting to get pretty long[1], with more and more of them having better performance, battery life, weight and screen resolution than the MacBook Air for less than $1000 if you're willing to deal with Windows[2].

I think Apple will have something new in the same space as the Air or non-Pro MacBook soon, but the options aren't great right now.
