Probably b8 but my personal reasons for not needing/using Windows (I used it up till about 3-4 years ago)
-I like the freedom (as in privacy/liberty) of Linux (could easily afford to pay for Wangblows but why when there's a superior option available for free)
-I like to use my hardware until it breaks and if I used Windows on my current 2010 laptop it might not work that great and lag and shit, whereas Ubuntu is lightning fast
-Windows load time are ass
-I don't have to fuck around with needing cracks for specialized software, virtually any good software package is available for free, the only time I pirate is when I play games, even then most good Linux games are open source and free
-Blows Windows out of the water when it comes to programming, no contest
-Less magical shit going on, when something fucks up there's usually a good reason why and it's easy to find out, on Windows you just have to hope the driver/OS developer wasn't a moron
-Telemetry
-Pooinloo ethics (which are objectively inferior to hacker ethics)
-Uses up a lot less space (I'm on a 64GB SSD so this was the killer feature for me, probably should have mentioned this higher up as it really made a massive difference to how I work, Ubuntu takes up like 5GB, Windows took up like 18GB)
-Easier to do virtually anything in Ubuntu compared to Windows, take something simple like full disk encryption.
If you ask me, the strong point of Windows was that shit just werked (usually past Win7 at least), but Ubuntu is basically the same now but better for the reasons I listed.
>38% doesn't mean its ahead of the others
Mathematics not your strong point then
