Ebooks vs paper

What are your thoughts on Kindle (or other electronic format) versus paper books?

I’ve got an unwieldy paper library and am starting to collect books in Kindle format. I suspect Kindle will be my preference for fiction, since I go through that quickly and it’s a lightweight way to carry a lot. Browsing is awkward in electronic format, leading me to think I’d rather have paper cookbooks, but the nondestructibility of a tablet in a case is also attractive in the kitchen.

Which kinds of books do you prefer to have in which formats?
