In Canada, with a Kobo, buying from Chapters/Indigo, the trade paperback is often cheaper than the ebook. This is my situation, and it means that the only time I buy an ebook is if I'm extremely motivated to read a book right now and I can't get it digitally from the library. If I had a situation where I was travelling and extremely space-constrained I might pay the premium for an ebook, but that hasn't happened to me yet.
All that doesn't mean I don't read ebooks, but that I don't buy them. The ebooks I read come from the library, (I'm a member of two libraries with great ebook selections), or are classics from Project Gutenberg or similar.
