I think the main reason that microfilm never took off is that it's an awkward tool for pleasure reading--just as the desktop computer screen is. Siracusa is right that people will read lots off of screens, even desktop computer screens, but he elides that into being willing to read many, many pages of the same work, in a row, on a desktop computer screen. It's not an accident that his preferred e-book reader form-factor is the handheld (first the Palm, now the smartphone).
