Regarding the feeling of something missing by reading on electronic devices, expressed in a few comments:

Some (not all) answers I was able to find in Maryanne Wolf's book "Reader, Come Home". Main concept there is what she calls deep-reading, a complex back and forth between different brain areas and the hemispheres, that needs time and is replaced by specific forms of skimming on the mentioned devices. In particular, the shift between hemispheres allows for integration into the reader's personal store of knowledge and, more broadly, into their own worldview.

The "wasted" time is essential for memory building and consolidation. Add enforced linear reading without immediate availibility to break the flow by googling/notifications/jumping to whatever, also consider haptics and more. Similar effects can also be found in handwriting vs typing, manual sketching etc.
