What operating system are you using (Windows, mac, linux)?

Windows is good for gaming, but i use windows and linux (arch) in dual boot, one for gaming, one for programing some things ^^

I have Windows 10 for gaming but I mostly use a Apple OS. I do a lot of video and audio editing.

i use windows most of the time, but i do have a few linux machines that i use occasionally

I'm using Mac Catalina. I like it somewhat although the bluetooth glitches and stops working sometimes smh.

I use all 3, they are all useful for different things.

As a FOSS person, I have been using one of the most lightweight distros, Lubuntu 18.04.
I have also used Lubuntu to revive old computers of mine. It would be impossible to run a 10 years old PC with Windows stuff because of the less system sources.
Using less system sources for the same task opportunity is a savior.

I am using Ubuntu 20.04 as my main O.S. I stopped using Windows a year ago because it is a RAM hog and doesn't utilize the resources as efficiently as linux.

Both win and mac are being used because of different situations

Windows 10. I still prefer windows 7, but 10 is growing on me.

ive been running windows my whole life i think
