People get headaches from flicker, not from a light source. Back when LCDs were lit by CCFLs that ran at 60Hz, that was valid. No tablet or phone uses a CCFL backlight, and very few laptops do anymore either. Many desktop LCDs and HDTVs do, however, which is why I suspect people are extrapolating from their poor PC/TV experience and saying they would hate backlit phones or tablets for reading without actually having tried them.

Call whatever you like... I and others are not talking about headaches, we're talking about migraines... only people who've never had a migraine will talk about them as though they are are synonymous - THEY ARE NOT!!! The last one I had started with holes appearing in my vision then a slight pain which over several hours increased to an absolutely totally encompassing agony which required the use of migraine drugs (NOT headache pills) and total peace and quiet in a darkened room for the rest of the day and left me only capable of limited functionality for the next couple of days... oh yes, there was NO flicker trigger...
And there is a difference between staring into a bulb and staring into a reflection of the bulb as it appears twice as far away... and what has that got with anything anyway as I explicitly excluded the effect of a mirror... it is a different form of reflectivity to that from a DIFFUSE surface such as e-ink or a book... how many books have you got that reflect an exact image of nearly 100% of the light/image acting on them???
