Large tablets have been around for nearly a decade now, and people that write novels and word files all day still use a real keyboard. If what you are saying was true, everyone who types for a living would use iPad pro or equivalent.

Secondly, patches and reboots are a problem, not a solution. Users do not need to replace switches themselves. My father is not an IT nerd, he uses his laptop for work. After the keyboard broke, he took it to a nearby repair store and they replaced it for $20. If in a few years it breaks again, he can do it again (ofc laptop might be worth replacing for performance reasons, but that's different).

To him software crashes are far more disruptive, he cant call Acer or Apple and give them $20, $2000 or even $w0,0000 and get them to fix a sound driver or whatever.

He just has to sit there and hope that some day one of the updates, without proper patch notes, will fix the problem. Leaving feedback on the forums is about as reliable as praying for rain or doing blood sacrifice to cure the plague.
