Finally getting to the point? It's not remotely close. The problem is the app ecosystem. Configurability. It pretty much will never get there unless someone does Linux on desktop Android style AND has some way to drag hundreds of MILLIONS of users onto the platform.
Windows has an ENORMOUS app ecosystem that is based around GUI configurability. Installation of 90% of tools is GUI by default. Not fixing crap in bash. Not this incoherent rabble of apps ecosystem. There are many major parties trying to reinvent the wheel in Linux and many parties that philosophically interfere with the ability to replace Windows like the free software movement. Until you crack heads and get them working coherently, Linux is NEVER going to beat Windows on desktop.
There simply is no reason for that many people to adopt a new desktop platform. It just ain't happening. Windows at this point is likely to be the last major desktop OS before some revolutionary desktop sea change occurs - if that ever does.
Ps Windows desktop marketshare is currently over 77% from what I can tell. Linux is < 1.7%. That's a complete and utter market failure. Sorry. But they should have been at least 30-40% a decade ago let alone now if they were remotely competent.
Okay, so I can see this as basically a troll post or you're just uneducated on tech history which isn't your fault.
So to put it shortly, essentially anything that can run on Android can run on any Linux distro. The GUI is designed around adaptability which is why multiple manufactures can make their own version of Android and the GUI still plays well with the play store. Variable GUIs are actually one of linux's strong points.
Now, you're citing numbers on the desktop side, what about other types of devices? If you include the Enterprise market for servers and the mobile market, neither apple or OSX stand a chance. If it wasn't for Google turning Android into spyware, WAY more people would be using it. Now, the beauty of Google working on Android is that there are now Linux distros that can use ALL the apps on Android in a desktop environment without you even having to think about how it works.
I 100% understand where people are coming from when they are uncomfortable using Linux because my first experience was with a KDE falvor of Ubuntu back in the mid 2000's. My God, I couldn't even get webpages to load properly without extracting binaries through the command line to make the browser work.
But now there are distros that require near zero use of the command line and it's only getting easier. You can also add whatever GUI to Linux that you want. I like cinnamon because it functions and works like windows. It took some getting used to but atleast control panel settings don't move or get hidden with every update
And to some extent, you're right about Linux market share, but I'm not going to a bar and asking people to switch to Linux. I'm on a tech website talking about how little personal education it takes to get Linux to function as a daily driver and a gaming OS. If we are all here to be tech enthusiasts then we should be well enough versed in technology to make these things a walk in the park.
There are 100% legitimate reasons why people should still stick to windows 10 or MACos, but that list is getting smaller everyday.
I've started on Manjaro because I like to tinker with things, but Linux mint cinnamon got me into the ecosystem because in many ways it was easier to use than windows.
If you have a personal preference or some software need where Linux isn't a viable alternative for you, that's perfectly fine. People choose Xbox or PS4 over exclusivity all the time. I know it's not the same but it also isn't that far off.
All I want to say to people is just install it on a jump drive and use it for a few days. It took me about a week to be sold once I saw all the games I play work flawlessly with Linux. It is kind of annoying I had to switch from libre/open office from MS office, but it wasn't that hard.
Sure, Linux isn't flawless, but as MACos and windows 10 become more flawed over time, Linux is looking better and better.
