Thanks for the suggestion, however Steam only collects information from people who use the platform. Not all desktops are used to play games or have programs associated with their launcher.

People use tablets and ARM laptops to do desktop work. Office is for Android and iOS, so they are included there.

I agree that the term "market" is not quite correct if we become somewhat fundamentalist, however it is a term that attempts to clarify user preference among the different options offered.
Consoles, servers, IoT, and so on don't count. These devices are mostly composed of BSD and Linux, and the chart only focuses on desktop users.

P.S: I am also part of the 1% of Linux ;)

Windows Phone and Ubuntu Touch are dead... 😅

Thanks for the annotation, I forgot to clarify that the measurement is purely for desktop use.

>Why did you choose that order?

There is no particular order, it was random.

>What constitutes an instance of an operating system usage? Are Raspberry
PIs counted? what about servers? consoles? smart fridges?

It is constituted by the daily use of the system on the desktop.Devices such as consoles, servers, and other IoT, do not count since most of them are composed of Linux and BSD. (They also do not fit in the desktop category).

Linux is obviously the king of servers. The graph looks at desktop users.

I am a computer science student, interested in data science. This is the first visualization I make and share ;)
