How about Linux on the new MacBook? It's a nice machine and my old lenovo looks a bit "unhipsterish" when I work in a cafe. Also it's heavier. But I live in Linux, so I would have to be sure it works.
I'm running Linux on a Dell XPS 13 (dev edition, FHD screen + i5 for power savings). Plenty of power for most of my laptop use, big "infinity" screen (thin bezel) making the machine small but screen big, and overall positive experience.
It's also driving a 34" screen right now, and not breaking a sweat. http://imgur.com/WvGwGo9
