I think all these points are valid. As someone who spent the first 30 years of my life reading physical books, the transition to e-books has been difficult for a lot of the reasons you mention.

I wish the author was more specific on what "reading circuit development" means.

The frustrating thing about e-book reading devices is how slow they are. Flipping to the table of contents or flipping around the book just doesn't work. Mobile devices, tablets and computers are faster, but the experience still isn't as good a physical book. And then there are distractions.
