The market is much more likely to copy a major success than a minor success or failure.

So, that's Dell, HP, Lenovo and Asus on the Surface Pro/Surface Book bandwagon and Dell at least looking at swivelling 2-in-ones (I'd admit that the Lenovo entry is more of an adjustable display...) but then the Surface Studio concept is much newer than the Surface Pro/Surface Book idea.
There's another thing about the PC world, though:
The Surface Books/Surface Studios are "prestige" products, and partly serve as reference designs for Windows.
If you don't like them, there are 101 other choices of ultrabooks, laptops, mobile workstations, gaming laptops, mini towers, alien-shaped gaming towers... You need a brick-thick laptop with space for 4TB of HD? It's out there. A mini-PC with a quad i7?
It exists. None of those fit the bill? Buy the CPU, Motherboard, GPU, RAM and storage you want, pick the case and spend an hour or so with a screwdriver (or have your friendly local computer geek do it for you). Then, if you want Windows
give Microsoft some money. Just because you don't want a surface doesn't mean MS has lost you as a customer (although there's always Linux - I
like Linux provided I don't have to use it as a desktop).
With Apple - you have an increasingly limited choice of a few ultrabook/small-form-factor systems or a 4-year-old semi-dedicated FCPx appliance (only apply if you have an OpenCL-dominated workflow). The new MBPs are probably great if your requirements hit the sweet spot, and the 27" iMac is still pretty good value if you want a 5k display, but if none of those float your boat
your only choice is to go Windows or Linux. (The Hackintosh community have done sterling work for little reward but you can't recommend running OS X unlicensed - and open to a crackdown at Apple's whim - as a serious solution).
I much prefer OS X to Windows - as long as Apple is also offering the appropriate hardware.
Back to the routers - there's actually one fly in the ointment with Apple's routers, and that is Internet connectivity and ISP compatibility: they don't include xDSL modems for phone line and FTTC connections.
For the sort of less-techy person who would otherwise really benefit from the "just works" aspect of Apple routers, my advice would have to be
use the router that your ISP gives, leases or sells you. Especially if you're going to get extra video streaming services from the ISP (some of them use multicast).
For starters, here in the UK, most ADSL and VDSL (FTTC) services now come with an all-in-one modem/router that connects direct to the phone - so you'll need to get a separate ADSL/VDSL modem and hook the ethernet from that to the Time Capsule (...and before you suggest it, the ISP routers tend not to have 'modem only' mode). Apart from anything else, for a simple home/small office setup you don't really want the extra plug, cable and wall-wart.
Then, if you have to call the ISP's help lines you really, really want to be using the router the ISP sold you if you want any chance of a fix. If you're tech-savvy enough to deal with that then you're probably savvy enough to want a 3rd-party router with more bells and whistles.
