Why no, there is no practical reason to get one of these. Why yes, I do really really want one.

Key quotes: "we break stuff before we know what replaces it, and we invent things before we know what they are for" and "If I’m thinking as a normal consumer, I don’t really care terribly much about what the future of ink on paper is going to be. I care about what the future of content is going to be."

Useful reference for the reasonably near future, I suspect.
