HarryT, I value your take on the topic in particular because I gathered from your earlier posts and/or signature that you use the IPad in a profession/job comparable to that of an editor (in German 'Lektor'), someone who works in a publishing house and does the editing of books and articles before they will be printed including communication and suggestions to the author. It's a professional field I worked in myself. The point is you always have to read [although I read on paper first while working there, second step was to correct (proof-read), shorten or clarify the text on the (word, not pdf) document on the pc].

And that's what I am interested in. The opinions of people who spend a substantial part of the day reading and annotating, basically regardless if it's for work or not. Academics, authors, editors, engineers, programmers, journalists, 'private scholars'. Regardless of your profession it comes down to the activity of reading and working with pdfs a substantial time each day of the working week.

It's not a job for me, but a hobby - academic research in Egyptology - but it's one that I spend several hours doing every day. I do, however, spend my working day as an IT Consultant using an LCD computer screen.

"One could put it like this: Objectively EINK remains the best for the eyes. If you want to work with PDFs on E-Ink, Onyx Boox is best, if you want to go for the device that is best for your eyes. But if you are okay with the second best solution for your eyes, then you go for the IPAD Pro because their screens and other features make for an acceptable reading and, above all, working experience, except if you have very sensitive eyes. So the IPAD gives you the 2nd best solution for the eyes and the best solution for handling pdfs."

I've never personally had any problem whatsoever reading from LCD screens, and it's something I've been doing for well over 30 years now. I prefer eInk devices for reading fiction on, due to their long battery life and sunlight visibility, but for use at home I don't have the slightest issue with LCD screens. Most people who have eye-strain issues with LCD screens do, I suspect, have the screen brightness set far too high.

I am sorry, if I get a bit obsessive about this, and I get it, if you, HarryT, say that the Ipad Pro is superb for reading pdfs knowing that you do not voice your opinion on the basis of a user profile who only now and then reads a scientific pdf or just handles his business correspondence (pdf) but reads and works with multi-page pdfs extensively many hours of many days of the week (also using scanned pdfs as I do as well).

It's not reading multi-page PDFs that the issue. My usage, as is typical for academic reading, involves having multiple documents open at the same time (or looking at different parts of the same document) and being able to rapidly flip between them. Unfortunately, all the eInk devices I've used are (reasonably enough) targetted primarily at fiction readers. They're great for reading one book from start to finish, but not good at all for handling multiple documents open at the same time. The Goodreader app on the iPad has a "tabbed" interface which makes it extremely easy to rapidly flip from one document to another.

Hence I read fiction on my eInk Kindle, but academic PDFs on my iPad.
