Thanks for all the replies.

Well, I read some stuff on my kindle dxg 3.2.1 but I find it not sufficient to read some image pdfs, it just does not zoom well. And I am not sure that more modern e-ink reader will provide sufficient zooming. The backlight is very useful thing, but still the greater screen and thus better zooming is a better feature for me. I asked ipad users about their experience with their tablet, and they also confirmed some minor experience of mine, the screen of ipad is not good for long reading, though suprisingly some people read it without any problems. How lucky they are. They can get just ipad pro 12 with all multiple features, graphics, 3G, and also reading feature, and this all in one device, and does not have to stick to different devices for different functions.

If I had had personal experience with Onyx new 9.7 model, and had found it suitable in terms of fine tuning of zooming, and perfect rendering of the color of the greish/blacking/oldish image pdfs, I would change my view, but I do not have it, and use only DX of this size, and so have to rely on my experience and feedbacks of others. So, at the moment I am leaning towards buying some 13.3 model.
