I'd consider a recently updated HP Spectre x360 with newest Kaby Lake CPU. In my opinion it's a better device than Dell XPS (XPS machines still do have very well known and annoying "coil whining" issue). Mentioned it yesterday in Makbooks related topic https://news.ycombinator.com/item?id=12808431

See details http://store.hp.com/us/en/mdp/Laptops/spectre-x360-211501--1 and video review https://www.youtube.com/watch?v=JZLEm3o9R5A and another one http://www.notebookcheck.net/HP-Spectre-x360-13-w023dx-Conve...

Also take a look at the Acer TravelMate P648 http://www.notebookcheck.net/Acer-TravelMate-P648-M-757N-Not... Though it's more like a solid working laptop than a fancy Macbooks competitor, but looks like a good device.
