I'm not saying this to be rude, so I apologize in advance if you personally take offence: In my mind, you're a complete idiot if you are an e-book consumer at this point in time. You essentially rent the book for a price often higher than owning a physical copy of the exact same material. All this for the slight mobility advantage, and instant purchase ability. You can't share your ebooks with friends. You run the ri…
First, the instant purchase ability is extremely important. It means that books gain some measure of equality with other forms of media (the internet, movies/tv, music). With a Kindle I can read whatever book I want whenever I want, which means that I read many more books than I used to.
Second, the mobility advantage isn't slight at all, especially for people who read a lot. If you're never carrying more than a single book around that's one thing, but I read 1-2 books a week, and a lot more (often 5+ a week) if I'm traveling. Even just during my daily commute, it's far easier to read while standing on the subway with a Kindle instead of a book.
Beyond that, I find reading on a Kindle to be far more comfortable than reading a book. The actual reading experience is much nicer than trade paperbacks, which are printed very cheaply. It's much lighter and only requires one hand to hold/turn pages, so I can more easily read while lying down, and the newest version has a very nice backlight, so that I can read in bad lighting.
There are obvious disadvantages, and I absolutely hate that DRM is still a thing, but the benefits absolutely outweigh any possible disadvantages for me. Anecdotally, it's the difference between me reading 5-10 books a year and me reading 50-100 books a year, and I'm a much happier person in the latter state.

Also, if you're not saying something to be rude, you should actually write like that, not add a disclaimer at the top of what you're writing. There were a lot of ways to get the same message across without calling people idiots.
