I think I didn't buy a Windows license ever. Got Win 7 free from my college and always could upgrade for free to the next version. I never used MS Office, mostly did use the Google suite. Games were the only thing that kept me, especially since I got more privacy continuous over the past few years.
I'm currently dual booting Win 11 and Linux mint as a test phase. Actually just running windows for the proprietary phone client I need for work. Otherwise I'm newly exclusively using LM right now. Though I might make the switch to EndeavourOS for it's rolling release approach and AUR.
Only thing I really hate is that there are some proprietary software like ICUE, L-Connect a proper scanning software for my printer including OCR (there is a version for Linux but it doesn't include OCR) or shitty driver support for my graphics card. But none of those are issues coming from Linux itself but rather from the lack of support from the developers. Also, I love DLSS and Ray tracing but seriously.. fuck Nvidia.
