Yeah, that’s why I said Office users — the core experience isn’t bad at all any more. It’s usually other apps which are pushing CPU limits notably. A big one recently has been video conferencing since a lot of schools didn’t used to need that at all, much less large classes entirely online.
Google Docs runs well on a Chromebook. As does MS Office online. The modern desktop has really turned into a terminal - it's jut using HTML & JS and works... pretty well.
