I've been considering this.
For a long while now, I've been a proponent of pen computing (started w/ a Koala Pad on a Commodore 64, had an NCR-3125 running PenPoint, I've used every version of Windows since Windows for Pen Computing so as to have a system w/ a stylus), but the recent Fall Creators Update having dumbed the stylus down to an 11th finger making text selection difficult for me, and very inefficient (I've had to roll back twice now) has me seriously considering an iPad (which would be my first Apple purchase since buying OPENSTEP 4.2 from them right after they bought NeXT).
Can't not have a full-fledged computer though, so the iPad would be used for mobility and pen capabilities --- I'd get Mac Mini and access it using the iPad Pro and Apple Pencil using Astropad Duet.
I'm almost to the point of just doing it, and probably would if I were confident of finding web sites and apps which could handle all my needs.
