It's a bit embarrassing really, I mean the pdf UX.
I understand they don't directly profit from it but there are a lot of people (ie. the people who wrote a majority of their non-fiction catalogue) that would popularize the reader, and use their commercial catalog through that.
Even if they spend a month of programmers' time (nigh impossible on such a limited scope), it's a bit large to leave it be while claiming they developed it with the users' input.
It is worse than what I helped make for Rockbox back in early 2000s, reading comics on my h120 mp3 player's 160x128 display
