I think the statement
"people don't get e-books."
is the biggest point here, especially if you expand the use of "people" to include publishers, booksellers, authors and software producers. In fact, so much of the discussion about e-books on this very forum ends up being back-and-forth over hardware and hardware issues (which is, of course, where DRM comes in) than over book sources, content, quality, etc.
His suggestion, early on, that it's the book that is ultimately important, and the delivery should be completely incidental, is the one thing that has dragged down the industry for so long. He suggests that fear was a major reason, but he backs off from suggesting that greed was also an issue. (Of course, we don't have that problem around here!)
Finally, he made a point I've reiterated many times: That the upcoming generations will be a lot better with these changes than the older generations, and as they come into power, the options that older gens refuse may be options younger gens embrace. The use of cellphones for more and more personal computing chores is a prime example of that.
