Live by Linux, but it's getting more Windowsy every day
I've been using Linux as a primary OS since Suze was bundled in a box with manuals, CD's and a cool gecko sticker (about 1999 I think), there's still nothing that can beat it in my opinion but distros seem to be going a bit backward and frustrating recently.
I'm on Ubuntu Mate 16.04, could never settle with KDE and it's glowing halos round everything or Unity and anything with a side-mounted task bar. Whenever I've mentioned performance of current DE's I always get a response that with today's computing power you don't notice how long a window takes to open/switch or a menu to slide out.... or the several tens of extra processes sucking life out of my laptop battery in the background. There must be a reason my out-of-date Crunchbang install lasts 4 hours longer than Ubuntu or Fedora when I'm on the move?
Add to this the PITA of systemd. I know somebody will pick me up on this, but it really is an absolute horror and I'm sick of spending hours looking for solutions to it's random problems it keeps throwing at me. Gnome is basically falling head-first into systemd lock in and likely KDE in the not so distant future.
.... then there is generally stability. Atril Document Viewer experienced a problem, Mate Panel experienced a problem, Firefox 52 being unable to handle Ebay's ridiculous background scripts (okay, probably Mozilla's fault, but it got shoved in my updates and Microsoft-style won't roll back), having to reboot each time I've used Gparted because the kernel didn't recognise blah blah blah....
I'm willing to pay for Linux, when openRC kicks systemd to one side, when OpenBox supports Wayland, USB file transfers don't grind to a halt and when Canonical will let me buy an end users desktop version of Ubuntu with at least some kind of direct online support.
Windows will never see light of day on my main machines again, but I'm getting to the point where TrueOS gets moved from my 'nerd' partition and pushes Ubuntu into the same box. Please Mr Shuttleworth, see if some of those developers you're looking at shedding can start working on ousting systemd from what was a fantastic OS.
