> Phones are not designed for reading, so dynamic layout or not, it will still be inferior to finely typeset document Personally, I find my phone to be my favorite medium to read prose on, not inferior to anything – including printed paper, which I never use if I can help it. It works for books and most webpages, but PDFs are a disaster. My second preference is my laptop. Its screen is big enough to make reading PDFs an acceptable experience, but not a great one. When viewing at an optimal zoom level for me, there's almost enough vertical space to fit an entire normally-sized page… but not quite. Which means I have to scroll. In the common case that the paper has two columns, I have to scroll down to read the bottom left of the page, then back up to read the top right, then back down to read the bottom right. Oh, and it's always great hunting for the figures in a paper, because of course they have to be nicely lined up in a corner of a page, even if that leaves them far from the text that references them. It's a compromise that makes total sense in print, but feels silly on a screen. So TeX's output is good in print but awkward on a screen. (It may not be limited to PDF, but I'm pretty sure all its output formats assume a fixed page size.) Meanwhile, HTML is good on a screen, but I agree that it's awkward in print. What we need is a format that's good at both, and that doesn't currently exist.
