Resolution is only part of the story. Perfectly laser quality characters are no use if too small to read easily. PDF scans of old books and magazines in the public domain are tricky even at 10". Note that a Letter or A4 size document needs 14" diagonal at a reasonable aspect ratio (not 16:9) to be viewed actual size.
I've plenty of PDFs that are excruciating on a 10" tablet, but work on a regular sized screen rotated to portrait.
Similarly a "Retina" resolution 12" laptop is much less useful than a lower pixel count 14" 1920 x 1080. For documents my 2002 laptop with 15.6" 1600 x 1200 is better even though the DPI is less, because that 1200 vs 1080 on a quite taller screen makes a big difference for PDFs. The 14" is a little small and 1080 just slightly not enough. The 16:9 is a step backwards for laptops.
So I bought a Libra (7") and a 10" Tablet at about the same cost as a Forma. The Forma isn't big enough, despite the similar number of pixels, nor does it have enough storage for scanned PDFs (Almost every genuine PD PDF is scanned). The Libra is as large as I'd want to read a novel. The Tablet has a 256 G byte micro SD card at an extra €40 approx.
