Did you ever pay to support the various commercial endeavors for a Desktop Linux that Dell et al. have tried? I haven't, for one simple reason, though a second builds on it: their hardware is always subpar (laptop or desktop) -- which I can't even blame them for if they're trying to get sales from the much larger market of non-power users, but then the price isn't that competitive either. Second I'm going to reinstall the distro to one I prefer anyways, or even if the same distro at least one that I'm sure is free of any bundled crapware that is supposed to make the experience more polished and seamless, so I'm going to do it on better hardware. The only time hardware has been an issue for me was, I don't know, 15 years ago with a laptop's built-in wifi? Linux runs on a lot of things, some of those things include laptops and desktops.

Why?
calling Android handsets and Chromebooks "linux computers" makes me cringe (versus "both android handsets and chromebooks make me cringe")
if that helps understand the context a bit more.
It's the tradeoff between mass-market UX and raw power and customizability, and Android/Chromebooks are at one end of the spectrum while what we associate with "Linux computers" is at the other.
Google is the only company who has championed Linux for mass market success, but calling Android handsets and Chromebooks Linux computers makes me cringe a bit. But that's what makes it great, being so modular and flexible.
On the flip side, Windows get bashed way too frequently. Say what you want, but since Win8 Windows has been fast, fluid and stable, and gaming and video performance are top notch. That's hard to walk away from when comparing to Linux.
