Netbooks, certainly Kindles, eventually smart phones, to some extent MP3 players (though certainly not completely), to a large extent newspapers and magazines, to some extent laptops (for purposes other than being work stations), to some extent TVs (we'll probably always have some large dedicated video display devices for 'communal' watching, but we'll lose a lot of the personal TVs in bedrooms and offices and such - though that will take time), to some extent peripheral devices like DVD players and game systems. Textbooks will become a thing of the past - students will have these kinds of devices and they'll 'rent' the content that is associated with a particular course, and be able to interact with it in ways that just weren't feasible before.
The way we relate to such things will change - we will come to expect them to conform to us, and come to us, instead of us going to them. When we lay on the couch, or in the bed, or sit in a chair, or on a plane - we will expect our media interface to be at our beck and call. We won't expect to have to go to the Living Room to see something we want, or to our bookshelf to find something we want, or to the store to get a magazine. And, once we engage something, we will expect it to travel seamlessly with us, instead of us being stuck where it is at.
