Actually, as an owner of a Kindle I find presentation issues to be a big deal. I generally only buy simple books for pleasure reading on the Kindle, and so don't really care about DRM (I probably wouldn't bother reselling the paper book, and I don't care if I can't read it again in 5 years).
Approximately 1 in 4-5 Kindle books I consider buying I don't because of reviews that say something is seriously messed up with the presentation (pictures missing or improperly placed, chapter divisions completely gone, tables with data messed up or missing, etc.). If I have these problems with simple fiction and non-fiction, I imagine the problem is even worse for the examples he cites such as cookbooks, schoolbooks, travel guides, etc.
