Good point. Thing is, most people get their e-books from Amazon which has a history of harsh DRM restrictions and removing them from libraries when licensing issues arise. I fully support DRM-free ebooks. That is part of the reason why I am working on my e-reader...once I am done I plan on writing a book repository software to work with it to make getting e-books easier. However the fact of the matter is that people who buy them DRM-free are a minority. The majority of people prefer the convenience of just downloading from Amazon over grabbing one from a DRM free store and porting it to their e-reader of choice.

My complaints about DRM aside, my biggest problem with OPs article on e-books is thinking that one is "superior" to another, when different people get different formats for different reasons. Some may like the idea of being able to carry tons of books around with them on a tablet, or being able to search text. Others might dislike these features, and prefer physically turning pages. Neither is "better" than the other, and I dislike people that DO think one or the other is inherently superior for whatever reasons.
