There is one forumite who has, in my opinion, a very balanced approach to the use of devices and advice. They generally read on a LCD/OLED display device and so reap the benefits of those devices, but because they periodically hike away for extended periods from possible device charging opportunities they have a reflective device for that use and so reap the low energy usage benefit of that display type. In their position I would probably try to do the same (of course, though, many cannot afford two devices for reading).
Contrast that with the plain anger of some in this thread (and in others too) when the advantages of LCD/OLED are stated and the claims of "too bright" are contradicted. How often does one see such anger directed at the often unscientific claims of some E Ink promoting forumites? Perhaps people who try to take a rational stance balancing the advantages of both display types without anger find themselves gravitating to LCD/OLED?
And regarding my claim that people generally have displays too bright and that many do not know how to correctly set it for long term comfort, that is not something I have made up (it sure does create anger in some here though
). I have seen overly bright displays for years everywhere on all sorts of devices, PCs and instrumentation, in offices and in industry, in darkened and even completely dark environments, and in sunlight. And the associated headaches, sore eyes, etc. too.
But in those environments the personnel are not married to some self fancied display type that they feel some strange need to defend, they need to do a job in comfort so are open to suggestions of turning down brightness, getting their eye checked, for example. Suggestions are not fobbed off by them as being a fault of the display although they may find it hard to believe in the first instance that taking such easily implemented advice will work.
Oh, and as leebase, I too do not care what people use. But I do care though that when a new person to reading devices browses these forums to help them in their decision should see advice that is not skewed. If one has an eye disease then if one is going to give advice then in my view one should disclose ones disability to qualify ones advice (as rcentros has done). If one claims they get headaches from WiFi, as several in these forums do, then perhaps they should be self aware enough to consider themselves incompetent to give sound advice on any technology, or at least make clear their tendency to psychosomatic disorders if they insist.
