Actually paper books are an inferior product for many reasons: 1) moderately large to large books are uncomfortable to hold after a while. 2) Fixed font size. 3) Take up physical space (i.e. you can have books and other kind of "publications" like magazines in a Kindle). 4) Unsearchable. 5) Every reader essentially has to "hack" something as simple as progress saving. >"they require no battery": This doesn't really make paper books a superior product. The same argument could be said of landline phones but that doesn't make them better than cellphones. >"accidental touchscreen events": Not all ereaders are touchscreen based, an in any case it's a poor, circumstantial reason. Your other reasons amount to pretty much preference, none of them make paper books categorically superior to ereaders.
