>and my experience is that PDF >> any other system for ebooks.
Are you speaking just about technical books?
Because I can’t imagine anyone trying to read a novel in epub vs pdf on a phone or epub reader and going with the latter.
I am mostly reading on a tablet, not a phone. I think if you are reading on a phone you are already screwed —- if people are “reading” on phones I think 80% of it is that you just read less.
