Ah, now I remember one more advantage of physical books over ebooks. Science proves that people read slower, less accurately and less comprehensively on screens than on paper.

I really have to agree with both articles. I can recall details from physical books much better than ebooks. When I want to find one particular quote from a book I can remember which part of the book it was in (middle part, bottom-left) then flip through the pages to find it. I can't do the same on ebooks, and my ability to recall details from them is MUCH worse.
