Mak Weiser of the Palo Alto Research Center (PARC) wrote this article over ten years ago, and while it might seem dated it's an interesting look at the push towards ubiquitous computing, i.e. lots of small computing devices spread through a house all communicating with each other rather than one or two large ones in a single room.
If nothing else it's interesting to see what's already been accomplished and what's still to come.
