Smart House?

So…do I really want a house that monitors what I do? I mean…what do I do at home what I want recorded for posterity? Will the Hal 2000 home warn me that I must be getting a cold because I have blown my nose in the bathroom five times in an hour? A really smart house would do well to stay out of my way, not notice what I am up to and just do the house stuff: keep out the weather, the crooks and the animals and keep it about 20 C. Cheap, too.
