Was using Win10, have been a Windoze user for pretty much the whole time I've used computers, which is a while.
Using Solus for games and Ubuntu for work. Had some issues and Solus isn't working well with PlayOnLinux (with Steam) but other than a few hicups it's been relatively painless.
Put Ubuntu on a second partition to test it out and after a month or so I realized that I hadn't used Windows once. I'm actually really excited to be using Linux full time because there's so much that I can use and it seems so powerful. Wasn't sure if this was the right subverse but I'll hopefully be spending a bit more time here!
