\tangent can you recommend what to look for in a tablet for mathematics? I've got a lenovo M8 - only 8", 800p, but I think that's OK; it's the insufficient contrast of IPS screen that makes my eyes tired (suggesting AMOLED or epaper) - but I don't know the cause for sure... What did you find?

I mostly use an Amazon Fire 10" for math. It shows that it is IPS, but it really looks good, imo. Do you have a big contrast between your screen and your room? That's a big deal. I run a blue light filter at night. I do prefer eink and anything oled looks fantastic, but the fire looks really good, well beyond its $150 price tag. Better than my computer monitors (which are nice). Are you reading tiny, detailed print? Is it just a resolution thing? Lastly, are you getting older (40ish) and need reading glasses? That happened to me when crossing 40. I could still focus sharply at reading/screen distance, but I got tired. I went through that a couple years and got reading glasses -- actually just weaker versions of my nearsighted glasses. I had the doctor dial in the focal distance for screen distance, then got another pair for 12 inches are so (for a reading a book up close). So I have three pairs of glasses, one for distance (everything sharp from 3 feet outward). These strain my eyes from 3 feet inward. You don't need reading glasses if your arms are long enough... I have computer classes dialed in at roughly 28 inches. I can read up close, and see nearly perfectly at distance. I'm probably 20/20 at distance, but with my regular prescription I'm around 20/10. Then the reading glasses for up close things. These are fine for computer as well, and just slightly more blurry at distance.

  Thanks! I hadn't considered room lighting - though I also need it bright enough for pen and paper. Resolution seems ok - I zoom in when needed, which is rare. Some pdf's have lines too long to fit on the screen, for the text to be large enough - but they are also rare. I think a 10" would solve that (held lanscape, 10" is basically A4 portrait width, if you zoom out the margins). So it doesn't feel like resolution is a problem - although some people say fuzzier text tires eyes.
