In my opinion, downplaying of technology advancement was unjustified. The cultural resistance may have some impact but only temporary. Cellphones got later widespread acceptance in the US due to better regular phone infrastructure compared with East European or Asian countries but it was inevitable.
For e-books the technology is still on the level of the first massive and expensive cell phones. We still don't have 10 inch color e-ink screens for the price of a standard cellphone. That rules out most textbooks on e-books. There is a lot of room for improvements. It is actually surprising to see how much e-book popularity has risen with the current tech. I think it shows clear tendency of masses to embrace better way of reading and the only obstacles are the technology that still needs to get better and its cost.
