I've switched to ebooks almost exclusively because I love buying books and have no physical space to store more books, and because I like taking notes about books as I read them, and ebooks make that a lot easier. It's also easier to search an ebook, and searching is useful now because my memory isn't what it once was. But I'm mostly not making an effort to replace my paper books with ebooks, except if I see a book I own that's on sale in ebook form for a couple of bucks, I buy it.

I exclusively buy ebooks I can convert to non-DRM epub format. There are conversion tools that work with the Calibre ebook management app. Converting Kindle books is hard, so I mostly buy ebooks from Kobo or ebooks.com or one of the smaller retailers of epubs. I store my ebooks in Dropbox. I read them on an iPhone or iPad using the Marvin app.

I can see how cookbooks might work better in paper, but I don't usually use cookbooks in the kitchen. If I want a recipe I print it out.
