With Microsoft continuing to play target practice with its own two feet, I expect Linux to become an even more viable alternative. LibreOffice is quite usable and games are quite playable using Lutris and Steam. I've been free from Windows for a year and a half now. Everything I do on both my laptop and desktop is now on Arch Linux using the Cinnamon Desktop Environment. There's no need for me to go back. I can even edit photos with GIMP. GIMP will do roughly 90% of what Photoshop will do.
If I searched my posting history, I'm sure I could find a /. post saying exactly the same thing... except mine would have been from around 2005, and would have mentioned native games instead of Lutris/Steam, and specified Debian Linux and KDE. And GIMP. I was really into photography back then and used the hell out of GIMP. I still use it regularly, though not as much because my camera doesn't get so much use.
My point? I don't really have one, except that these sorts of predictions have a long history of proving to be wrong. Hence the forever meme "Next year is the year of desktop Linux!".
That said, I dumped Windows in early 2002 and I've never looked back and never regretted it, so Linux is and has been a completely viable platform for a long time.
