Programmable thermostats help save money by resetting the temperature when homeowners are asleep or away. But setting them up can be painstaking, and 89 percent of users never get them out of manual mode. The Nest thermostat requires almost no setup and teaches itself when to adjust the temperature.
It starts by building a schedule. For the first week, users change the temperature normally. The Nest notes their preferred at-home temperature, say 72°F, and also determines appropriate “away” temperatures—60º in winter and 80º in summer, for example. To account for conditions outside, the Nest checks the weather over Wi-Fi, and its indoor humidity sensor tells it when to kick in the fan for comfort. If everyone leaves, a motion sensor signals the processor to activate the away setting.
Even small tweaks can save cash. A change of a single degree from the preset program can reduce power consumption by 2 to 5 percent. The Nest also has a ZigBee wireless chip, so it can work with smart meters to turn on the A/C or the furnace when energy is cheapest.
The incredible innovations, like drone swarms and perpetual flight, bringing aviation into the world of tomorrow. Plus: today's greatest sci-fi writers predict the future, the science behind the summer's biggest blockbusters, a Doctor Who-themed DIY 'bot, the organs you can do without, and much more.

At $250.00 I think it would pay for itself in two years. It should last for decades. People like to talk about creating their own energy and going off grid. This is one of the building blocks to realize that kind of dream security and self sufficiency.
I pay a lot for gas and electric. This could help. When I'm home I want my family and I to be comfortable, and that's my responsibility. When the house is empty, now that's a nice opportunity to save money. It's kind of like turning the car off when I'm not driving.
I don't worry about climate change, but the math is the same: More efficient personal energy use means a lower energy bill.
For more info on this thermostat and how it relates to Apple's famous click wheel, see PopSci's article from Oct. 25, 2011:

Engadget and many other sites also had articles about the Nest back in late October, and on Nov. 30, 2011 the New York Times ran this piece:

I had one of those ultra-high efficiency gas furnaces installed last winter,along with a programmable thermostat.Both the installer and the manufacturer do not recommend programming the thermostat to a lower temperature at night and when we are at work.They made noises to the effect it would put extra wear and tear on the furnace and I wouldn't save that much anyway on my gas bill.All I can say is WTF??
There is nothing artificially intelligent about this thermostat.
I love my 2 Nest Thermostats; easy to use, extremely efficient, great iPhone app and it looks so sexy. I'm on week 3 and look forward to seeing the savings when I complete my monthly energy usage analysis. Last night, I bought 3 more on eBay for family members (late holiday gifts).
My girlfriend and are environmentalists and during the past 2 years, we've focused on reducing our impact on the planet. Our home is Earth Craft certified (4,200 sq. ft.) with 90% of the lights replaced with LED (Home Depot loved me that weekend). I drive an electric vehicle (maybe 2 after Tesla debuts the Model S) and will be exploring the addition of solar panels this year. It is amazing to see how our energy bill has decreased so far due to our energy saving upgrades (even with the EV). We've implemented water conservation upgrades, as well.
I can't wait to see what Apple, Nest, Tesla and other visionary companies come up with next.

AVR22,
As much as you project how electrical efficient with your electrical devices all become mute as you live in a grossly oversized home (4,200 sq. ft.!) with a desire to buy to extremely expensive Telsa S cars. You are a rich snob, pretending to be efficient. Your comments are a joke.
True savings comes all things considered and in your mind you seem to leave off the cost of your giant home and expensive vehicles and upgrades of your water system. You just bragging your electrical bill is low and forgetting the initial cost factor, which is part of the reality of the cost.
