Bought two, here is my review: February 25, 2012

A beautiful product brought on the market by the designers of the iPhone who intend to make this thermostat just as slick.
They are almost there.
The packaging, marketing, features, quality and appearance are all Apple quality, as is the typical easy installation. Online videos and included tools generally make it a snap to learn the intricacies of 24 volt wiring sufficient to replace your thermostat.
It is a new product and there are issues as with any new product and a start up company. Both Nest thermostats purchased a month apart updated themselves with the latest software....and then went into a download loop, endlessly updating themselves with no way to reboot other than calling the factory and having them do it remotely. This was done quickly, within a few minutes so they get a pass on that one.
The second issue was a no-go item that was ridiculous: the second unit did not work for my home. This in spite of me taking a picture of the wiring and explaining in intricate detail that this was the slave end of a two-zone HVAC system. They wrote back and stated that my photo showed that it worked, whereas later they acknowledged that it did not and the help-line person was "new". This after removing old thermostat, messing up the plaster and spending two hours troubleshooting. I looked around their web site and they now list about ten popular modems with which the unit will not function, at least online. They further state that "99% of the installations do not require a "common" wire." In other words 1 out of every 100 people who buy it will discover that the information provided was incorrect and they will need to rewire their house in order to get this unit to work. Others will have to change their modem. Incredibly, and un-Apple-like, they blame the modems rather than their software.
I decided to replace the zone panel in my house, about $400 item as the previous one was aging. Both Nests now work fine and the second automatically joined the first on my iPhone remote app.
In summary this is a beta unit which will probably work on your house, but for many it will not, I would explore their website looking for known issues before buying. They did offer an immediate refund and emailed FedEx labels in case I wished to return it, so good points for correcting the tech snafu.
After those unfortunate hurdles it works perfectly, I wake to a warm house, it learned what time I rise, checks the outside temp via the net and then allows sufficient time to warm the house based on its experience of heating time. If I leave for a few hours it senses this and lowers the heat. When away for a week I let it drop to 50F and then call the Nest units via my iPhone an hour out. Presto, come home to a warm house.
It is clearly the future, but presently its like an 80's computer: great once you get it working.
