Except it's not. At least not until someone starts making aluminum unibody laptops with Retina displays running some enterprise Linux distro in which everything on the desktop "just works" including printing and networking.
What's wrong with all the PC laptops is an attention to detail. Just have look at the recent Dell XPS thread. I mean - coil whine? In 2016? Seriously?
The other issue I had was with external monitor was, that the primary display for the login screen was the built-in display, not the external monitor (that's my subjective preference. After login, the arrangement was according to user preferences).
Both certainly not earth shattering. If other laptops or computers have more serious problems, that's issue to be solved by their manufacturer. They are selling their wares to you, after all, why would you accept incomplete support?
15" HP Spectre x360. UHD display. Option for double the max RAM in the new MBP. Several other nifty features, including an aluminum body and somewhat replaceable components without all of the glue nonsense you'll see in Apple products.
