FWIW, I'm using a 1920x1080 14" screen when not on a 4K 28" screen. Both with almost identical pixels per degree. (They are identical dot-pitch, but I don't use exactly the same viewing distance for laptop vs desk...)
I would be absolutely aggravated to work at half the linear resolution. I would tolerate it for some fast-paced game as a practical tradeoff for framerate, but not for text or static image viewing.
I have seen a 16" 4K laptop and considered it overkill or even impractical, i.e. pixels are too small to resolve and naively scaled icons or text are unreadable without a magnifier. But my usual screens described up top are above that threshold for me, and I can resolve single pixel gaps much of the time.
