Yeah, do we really want to run an open garbage fire of an OS that is known as Windows 10 for a daily driver? I know I'd get murdery if I lost all my hot corners, multi-desktop, etc cause that is what makes me productive. Other people who don't like Gnome 3 take pleasure in using i3 or AwesomeWM, which both are major steps up over Win10's UI.
At this point, the Windows platform is a rotting cesspool, the devs focused on it know its growth has stopped (but often are clueless about how to move forward), package management is not a thing, and Microsoft has added so many anti-features that it is a pain in the ass to live with.
Multiple desktops are built in. If you spent any time on the platform you'd understand that Windows under Satya Nadella is good stuff. He is the anti-Ballmer.
Debian/Arch are both fairly lively, if you want something battle hardend you'll use SLES like Walmart, Kroger, Fred Meyers, Vons, <Fill in major retailer> uses. The desktop is in stasis though, and iOS as a platform is unlikely to grow massively over the next few years.
Android is frankly another rotting cesspool of Google's making. Where Microsoft & Apple are able to provide years of updates to every model of phone their software runs on (with MS literally working with the same vendors as Google), Google has successfully ensured that outside of Nexus devices, updates occur rarely if ever.
Sure, but even 2014 phones like the Lumia 830, 929, et all got upgraded to W10P, Microsoft has made much more of an effort than Google to support 3 year old hardware.
Well, you know, they _already_ are. We don't have to wait for anything. And even cheaper, if you can avoid paying the windows tax ;)
