In the corporate world, there seems to be a shift towards thin clients running whatever OS works best (homegrown Linux, ChromeOS, macOS) and beefy Citrix servers, as well as another shift to SaaS/on-prem/on-own-cloud web applications.
Guess we're in a revival of the 70s/80s mainframes with dumb terminals again.
I don’t know. I bought office for my Mac 4 years ago and used it maybe twice. Google docs might not be quite as good but good enough for most things. I also hate looking at the ribbon (but that is just personal preference).
Yeah, for home/personal use they're all the same, and many people don't own anything Microsoft in that arena - Google docs from a iPhone/Mac/Chromebook are often "good enough".
Businesses they still have a stranglehold, but even there I've noticed it loosening.
