Arguably a lot of non-techie personal computing has moved there.
A lot of people are phone+tablet only, no desktop or laptop. As a result they are already living in a thin-ish client with fat server for storage/app/etc from their ecosystem of choice.
Not great!
Eh. I have newish Apple Silicon MacBook up in my office that I mostly use for multimedia work.
But I spend the most time on a 10 year old MacBook on my dining room table that I basically use as a web browser because that's mostly what I need.
Thin in form factor only! Phones and tablets represent the cutting edge of what humanity can mass-manufacture, and prices and difficulties are only going up.
