Already has if you count the unknown portion (which are unrecognized Linux distros). The Steam Deck is perhaps using some funky user agent that isn't recognized according to this: https://gs.statcounter.com/os-market-share/desktop/worldwide
And from the looks of things, Windows is on the decline. Linux and Mac are actually beginning to rise. Unknown are generally unknown Linux distros, and then there is ChromeOS and the recognized Linux distros. Together, that makes Linux about 13%
According to that, Windows' world wide market share is now under 70%. It lost 6% in the past few months starting in December.
A lot of this I find have to do with Valve pushing for Linux gaming. And there is also ChromeOS too (which is Linux). Then there is the unknown portion (which are mostly unrecognized Linux distros). That altogether makes Linux about 13%.
Really, it's the end of an era were Windows is actually relevant for the majority of PC gaming. And with people hating Windows more these days, they are weighing their options from the looks of it.
I don't know how people can use their computers at all given the BS Microsoft does these days. Like, why do people put up with this if they really don't have to and could just use Linux? I mean, even Valve chose Linux over Windows for the Steam Deck.
This is why you show them. I did. And they were fine with doing it.
But if someone is like my brain damaged sister (who drinks their lives away) and is incapable of grasping any information, I make a simple script with just a single command (that I put in a folder called 'scripts' under root) to run at a specific time in the background to do the updating (Typically during hours of non use). The only time it really has to be rebooted is when a new kernel is installed. Well, I let the user take care of that whenever they reboot, or shutdown their machine.
In fact, to make life easier, that is what I do for all of my household computers so that I don't have to think about it (because I am lazy).
