On desktop, I have the option of scrolling via spacebar or page-up/down keys.
This is reasonably determinative (the scroll distance is the same in each case), convenient (it's easy to hit those keys), and not confusable with other intent actions. That last point is key as very often when I'm attempting a scroll action on a touchscreen interface I instead commit a click action (usually navigating off-page). Which is maddening.
On touchscreens, not only can I not scroll by a prescribed amount, not only is input through an onscreen keyboard completely crippled, but there's an ever-present drag/click ambiguity which on Android at least (and from my limited experience with iPhones suggests there too) is everpresent.
Add in e-ink, and there are the additional levels that refresh rates drop low enough that following scrolling is tedious, and the display technology makes the many, many paints of a long scroll expensive in terms of battery life. Web browsing drains battery at 10x the rate of my e-book reader.
Einkbro at least mitigates some of that. Going back to Firefox or Onyx's Chrome-based browser is excruciating.
