I think a similar effect has been why power generation and efficiency systems (solar, "geothermal" heating/cooling) have been slow to catch on—for every buyer who sees them as a nice thing there's another who's turned off by them, and another who doesn't care enough to pay much extra. And even the ones who think they're good probably won't pay the pro-rated cost of putting it in, so you're still losing some money. Kinda like having a pool. Also why builders don't usually put that stuff in when it'd be easiest and cheapest, I think. Even at those lower costs they can't make the money back when they sell. So they're a good idea if you think it's very likely you'll stay in a house 15+ years, but not so much otherwise.
