I do! This doesn't make sense to me. I have a Galaxy Note 12.2, and it's great, but bigger would be better (it's not quite A4). I also have a 12"×9" Wacom Intuos, 12" Surface Pro, 15" Surface Book 2 from work. All of those would be even better bigger (but the work laptop wouldn't fit in my backpack any more). I have a small Wacom tablet too, and it's too small to be very useful.
Yeah, I am a pro artist and I have played with screen tablets and I do not like the way they make me hunch over my work surface and ruin my back, I really like that I can have my screen at the proper height above my desk and my tablet at the most comfortable place on my desk. No slouching, no achy spine, no ending up with nose prints on the screen because I hunch closer instead of using the zoom capabilities.
Devices like the Galaxy Tab S6 are basically a very powerful Android tablet with low latency high precision pen input (also does pressure and tilt detectio) via the supplied S pen (uses basically the same battery free technology as Wacom tablets).
As I mentioned, I have two graphics tablets (i.e. without screens), both Wacom, one large and one small. The small one is not very useful, and the larger one (~A4 drawing area) would be even more useful a bit bigger.
