I personally kind of like pdfs. PDF Expert on the ipad is pretty great; it crops things if you want, and I find pdfs good for annotation. My impression is that a lot of academics like pdfs for similar reasons (there are at least some valid reasons why they are popular).
There are also other programs that read pdfs aloud, which are kinda nice, though I’m sure similar exists for epub/mobi.
