Conjecture: this is a tech-centric viewpoint.

I have quite a few lawyer and doctor friends who use tablets first (usually with a BT keyboard) and only break out the computer when they need it for some very particular reason.

If you don't need root on a beefy machine and/or Windows-specific software, then a modern tablet with a bluetooth keyboard gives you more than enough compute and all the applications you need to be productive. Often with a better UX.
