Personally, I don't buy physical books anymore, though I so have a (small) library where some old books would be hard to find online.
Visual bandwidth: I cannot relate, I read just as fast on any screen as on paper, with no noticeable eye strain.
Pictures?
Compatibility: how many old books you own are not available in digital form?
I don't know. I shall check.
ETA: I have checked. Of the last 30 books I bought (a number decided by "ok, that's enough"), 13 are available as e-books (determined by looking them up on Amazon). Every book in the sample published since 2010 was available on Kindle; only two books published before then were (2002 and 2006).
