PDF really is the worst possible choice for a general-purpose eBook because it's tied to a specific screen size. It was never intended for use as an eBook format - it was designed - and is good for - a portable reproduction of a specific size document.
PDF is both a format and a container. I am beginning to believe the first poster has this very confused. He seems to not care about fonts but only a high resolution display which means he is using images rather than text. He might as
well be reading books in gif or png format. There are better containers than pdf for these kinds of tasks such as comic book formats.

PDF can be a choice for books if it contains text that is reflowable and if the reader supports reflow. Unfortunately most readers other than the ones from Adobe do not support reflow and even the Adobe ones require that the text be tagged for reflow. (There are ways to tag a file after the fact but this is beyond the scope here.)

While your statement about a general format that is page specific being a bad thing is true it is also true that most readers use a page specific format that is specific for their reader. This is one of the real problems that must be addressed before a universal format like epub can be used natively as a book format. Real books are pages. (This probably deserves its own discussion somewhere).
