There's a sort of disconnect between stuff that's part of the machinery of a house and the tech gadgetry world. House parts like central heating, taps, toilets and such tend to be very standard and long lived. How long did indoor toilets take to get traction? How big an advantage are indoor toilets over chamber pots? A "gadget" is very flimsy feeling compared to a toilet. IE, I expect the toilet to work in 20 years, but not an ipod. It might get clogged, but any plumber will be able to fix it. I think people are hesitant about installing ipods as part of the core infrastructure of their houses. What happens if your windows system won't connect to a router you buy in 10 years. Who will fix it? What happens if wifi becomes obsolete? I don't think I'm explaining this very well. Merging gadgets with houses is kind of unnatural. They operate at different time scales. Tortoises and fruit flies.
