Work. Software development is so much nicer on Linux and I grew to really enjoy the power and flexibility of the terminal. I started with dual boot on my PC and eventually deleted my Windows partition and went full Linux.
Many things have substantially improved significantly in the last 10 or so years such as gaming, drivers and overall desktop user experience to the point where I dread trying to use a Windows machine. Plus I'm pretty comfy now and like that I have full control over my machine when I use Linux vs whatever spyware MS is trying to shove down people's throats.
