No Desktop only. There were articles about the 10% recently. India has been 15% for a while. Steam Deck and SteamOS seems to have given a boost to Linux adoption in the last 2-3 years

I cannot find a source for the 10% claim, highest I found within a minute of searching was ~7%

There are reports from March 2025 that show 2% however I did not see how that number was reached.

On Wikipedia they show 3.9%(rounded) and a giant unknown number. https://en.wikipedia.org/wiki/Usage_share_of_operating_systems

I'm convinced that it becomes much harder because every operating system has a different name for the user agent.

My speculation is that most data is just pulled from cloudflare. However I got bored at this point and only found macro statistics like Mobile vs Desktop or the browser application used.

Pretty cool information though.
