About the only things I still buy as paper are picture books (Shaun Tan and similar). Many of the books that I have in paper I now have as ebooks too: the ebooks are what I read, the paper books are what I look at.
Just recently I was telling someone that the thing I miss most with ebooks is the selection from a physical shelf. The virtual shelves/folders arrangement - especially on e-ink devices - is so much less ... real/tactile than walking the shelves pondering what it is I want to choose next.
All that said, while I have an obvious preference for my e-ink Kobo reader when it is appropriate for the material, it remains a simple fact that that it is not appropriate for many things I want to read. Magazines typically demand colour and size, so too do picture books.
So, as ungrateful as it may seem, I don't feel spoiled by e-ink displays. They are currently the best compromise for serious reading of narrative text, but that's a fairly narrow field of expertise.
