After some time reading with the Forma I am tending towards selling it
. Cannot return thanks to Rakuten Japan’s medieval return policies, grrrr. I read in various settings from sun light to artificial light and in the dark and have the feeling that the text is not “calm” for a lack of a better word. I read screen to screen vs. my old Kindle Paperwhite that did not show this effect and had a calmer display. Light color, sharpness, light uniformity and basically everything else was much better (unsurprisingly) in the much more modern Forma.
I also did a “blind” test with my wife handing her both the Paperwhite and Forma asking how she likes the new reader. I didnt tell her about the whole PWM thing but she had the same impression.
Dunno if it is my mind playing tricks or not, but now that I am “tainted” it doesnt make much of a difference whether it is a real or just imagined irritation.
