@wiredfire for home I use Libre and Google Docs (yeah, I know Google whore me). For work I do use 365, but I’ve never felt compelled to use it at home.
OS wise at home I use Pop!_OS and ChromeOS mostly, at work mostly MacOS (which I don’t love, but it beats Windows).
@gpowerf can’t deny how useful Google is! Been on gmail for forever and not moving any time soon. Calendar and contact sync, and shared calendars, has been the cornerstone of my connected tech for 15+ years now.
