I love watching shows about a smart house. A house that can do anything at a touch of a button. I do feel that most of this will be available more and more in the future. Some of it is a little far fetched.
I think that technology like Crestron provides will allow for smart homes to be a possibility. The touch screens that are available today, will easily integrated into homes of the future.
I am sure that there are some smart homes available now, but I know that it will be more and more available as time goes on.
