That's all good and nice but it's been almost 15 years when the first Kindle appeared with a promise of affordable e-ink book readers for everyone. Fast forward

That's all good and nice but it's been almost 15 years when the first Kindle appeared with a promise of affordable e-ink book readers for everyone. Fast forward and it seems the "affordable" part still applies to the tiny 6 (or maybe 7-8) inches screens, and those who need to need to read anything technical with formulas and diagrams have to pay much more. I don't want anything fancy or "remarkable", just a simple A4 screen allowing me to read technical papers without using a magnifying glass or clunky workarounds. (Sorry for an unrelated ran, I just had to get it off my chest!)
