I'm a big fan of thin, fanless machines, and have both a 12" MacBook and a Surface Pro 5. While it's much less powerful, I find the MacBook more pleasant to use (even ignoring MacOS vs. Windows 10) -- way better trackpad, keyboard and screen are rigidly attached to each other, wakes from sleep faster and more reliably. The Surface Book solves most of these problems (and, IIRC, has fanless variants), but I think it's too bulky due to the 13.5" screen and hinge design. I haven't seriously considered a Chromebook due to the software limitations or the iPad due to the lack of a mouse cursor (also software limitations). In short, with the 12" MacBook discontinued, nobody's making a notebook I'm interested in at the moment. That's fine, though, as my 2015 MacBook is still working great (especially since I just had the battery replaced) and presumably I can still get a refurb if I drop this one in a lake or something.
