I actually find myself buying more and more ebooks lately. I find it really convenient for various reasons, including Whispersync (which is quite useful). Also I travel a lot and am in the process of finishing multiple books, so it's obviously convenient to not have to carry giant books around.
I think a lot of factors are influencing this trend, but I don't buy that DRM is the problem. As rude as it may sound, I doubt most of the general public even knows what DRM is. Well, the data itself shows that the majority of consumer book sales are going to paper, so that argument may be moot anyway.
Newer generations probably won't purchase nearly as many paper books (or digital, even) as older generations. It'll be interesting to see how it plays out. The market will probably shrink and be taken over by short-form work designed for tablets and e-readers.
