"Disclaimer.. not a Win10 user. I'm in the Linux world with Win7 for a VM. Happy as a hog in a waller as they say and not looking back."
And what's the marketshare and intended userbase of your perfect Linux heaven again? Oh, right. Small marketshare, and aimed at geeks and webserver owners. So it's not viable as mainstream OS. Been there, tried that. Some customers get used to it, most don't. Most of my customers are music producers and photographers. No native Photoshop support, and Cubase runs like crap on Linux.
Don't get me wrong, I'm a geek and webserver owner, and run Linux. But when things go badly wrong (and with kernels and drivers they often do in Linux) normal end users don't want to be faffing, or even know how to faff, with a terminal, and all the rest of it.
Windows may be beta software, but where's the alternative for your average Joe? Mac OS? Don't make me laugh.
