People think it is a must have, but at some point I postponed getting office until I really needed, and use libreoffice meanwhile. It's been years, and I still only have libreoffice installed.
I don't have any office apps installed on my personal computers, and haven't needed them in at least 6 years. Office apps are for office work, and I'm definitely not doing that for free on my own time and equipment.
I was a windows user until last year. Work has me migrated to Mac and at home I just can't be arsed with Microsoft anymore. I won't ever install Win11 and with Proton I probably won't have to.
