Sorry to burst your bubble ODelphi, but your entire premise seems to be that annotations are of paramount importance to every person who reads. I read to be informed, and to be entertained, but in none of my recreational reading do I ever feel the need to make annotations. I also have no desire for the Android e-readers whose eventual dominance you consider "inevitable". E-ink is, for me, an awful display medium for any of the functions that my Android tablet performs so admirably - including reading PDFs. Currently of the 850+ books on my Kobo exactly zero are PDFs, a number I am certain will double or triple over time.

The simple reality is, different people have different reading habits and thus prefer different tools to fulfill their needs. To describe users whose usage matches your own as "awake" and "vigilant" (both complimentary adjectives) implies that any who don't share your preferences are therefore not awake or vigilant. This implied insult may or may not have been intended, but it could be avoided by phrasing your posts in a way that recognises that reading is a very individual pursuit, with no one "right" or "best" solution.
