Pros + Very easy setup
+ Gorgeous design. Sleek, modern, low profile, simple interface
+ iPad, IPhone control - account setup was a snap, with immediate recognition of the thermostat I installed.
+ Moisture reading - ability to see % humidity
Cons - Lack of recirculate seems like a basic comfort feature that is missing and causing a net greater consumption of energy
Summary I know most people see the price tag and its sticker shock for them. What I don't understand is how they don't have the same sticker shock when they get the heating bill in winter or cooling bill in the summer depending on their climate. If you are a savvy person and have no trouble burning through the scheduling on a limited button unit, you are ahead of probably most households.Edit:
The one thing they have nailed with this thermostat is the ease and access to setting the schedule. Probably the single most important feature of any thermostat. If you have people at home during the day, the learning feature may work better for you. But for folks with set working schedules likes myself, the pure ease of setting the schedule vs learning the programming method of traditional thermostats can be time consuming and a turnoff for most people.
The reality is you will need to tweak the schedule continuously for the first few months, especially after you realize how finite you can dial your schedule into what you can find comfortably acceptable while reducing your energy costs at home. The constant schedule tweaking would be a pain in the rear on most traditional thermostats vs copy/pasting your weekday and weekend schedules across the rest of the schedule with the Nest. I bought one for the gas furnace in a home I recently purchased, and had no history to figure out how long it took to heat the house and how efficient the home was at retaining temperature. The history gives you the ability to view how often the furnace cycles on and off allowing you to fine tune your schedule.
The unit is flexible as well. Unfortunately my original control unit was placed in a part of the home where not a lot of traffic traveled next to the unit. Therefore the motion detecting Passive Infrared (PIR) was really not working well to determine when to set my auto away. This could have been remedied by running a new 4 pair wire to another higher traffic part of the home, but I ended up killing two birds with one stone. I had a gas log fireplace in a high traffic area without a remote control or wall switch, so using a honeywell fan control center I was able to wire the low voltage Nest to the adjoining wall of the fireplace to control it as well as its line voltage 110v blower fan, giving me control over two heat sources in the home and allowing me to turn on my fireplace with my phone/tablet/computer.
So the second Nest thermostat coordinates my auto away with the first nest thermostat. Could I have hooked up another type of thermostat to do the same thing? On and off functionality, yes. Integration of motion detectors in one system, no. I've even considered buying a 3rd unit with a separate transformer to operate a line voltage electric wall heater I have in the basement. My only gripe is the motion detector seems to detect around 1-2 feet away. In a hallway this probably would be sufficient, but in a more open area this is more limited.
Supposedly the 1st gen either had a better motion detecting sensor or the threshold was set to detect further away. I do wish Nest would give access to users for viewing a longer scope of the historical data, but obviously that would entail they grow their server farm to support it. Not a deal breaker, but for what the the Nest provides over traditional thermostats this should be improved as an offering.
New Features in future revisions: Weather forecast with outside ambient temp, since Nest is pulling zip code information. Have a 7 day forecast using icons depicting weather types in a circular clockwise pattern replace the dial until you actually click the dial to change the heating/cooling source temp. It's possible this is a limitation of limited power stealing some setups require, but would be nice to see.
Overall this thermostat is a nice offering to the home automation folks and getting everyday people comfortable with changing a few wires and installing it themselves. They've turned a product that is perceptibly known as a device requiring an HVAC professionals assistance to install into a task everyday people can figure out which is probably what is most appealing to the iKoolaid folks of this world. Honeywell will wake up one of these days and realize that their competitors are bypassing their dealer networks to do simple installs.
They will lose market share until they can come up with a product that doesn't require the same installer based support with its associated costs to install these devices with additional features. Can you do more with a complete Honeywell system? No doubt about it. But people know they are looking at thousands to get into these types of systems, mostly in labor to integrate it all together.

Pros So easy to install and use. Gorgeous interface. I often stop to look at it just because it is there. Its like art on my wall. And it does a smashing job at heating and cooling. Oh, and yes, I have seen a savings in my energy bill already.
Cons Price. I needed two for my house, so that's a whopping $500. If you can afford it, it is great. But it is a lot of money.
Summary If you can afford it or you can look at the long term savings, then get it. It is sadly one of my most favorite gadgets in a gadget filled house. The iPhone/iPad App works great, too. The most fun you will ever have with a thermostat. If that doesn't sell you on it, well, yeah...

Pros It looks great, has an intuitive interface, it's simple to set up and use, and WIFI built in means you can control it from the a computer or your smart phone.
Cons Pricey, but it seemed comparable when I priced other thermostats with WIFI capability.
Summary I saw the NEST thermostat mentioned on CNET last year and checked into it. They were sold out so I entered my email to be notified when they were available again. I got a notice that they were available and decided to take the plunge. The ability to control the temperature from our smart phones was one of the big selling points for me. You can be heading home, check and adjust the temperature in preparation for your arrival. The learning function is nice when you are on a regular schedule, but it still tries to learn even when you aren't. It is expensive, but when you check the price of other WIFI compatible thermostats, it's about right. And it can be modified, just like a smart phone, so new functionality and enhancements can be added in the future.
Pros Easy to install. Well made. Remote access. Easy to use. Informative. Cool looking. Firmware upgradable for future features.
Cons Price. I debated the cost, but am happy that I bought it.
Summary Much higher quality product than any of the other thermostats I've seen at Home Depot, Lowes, etc. Comes well packaged with easy to understand instructions. Very easy to install and set up. The Nest replaced a nice Honeywell 8500 touchscreen thermostat that I had for years. I set the Nest up with my current schedule but did leave learning on. So far it's working as advertised. My thermostat is located in an upstairs hallway so I disabled the Auto Away feature as we spend alot of time in the family room and kitchen area. If you are anywhere near Nest in your home, the Auto Away feature looks like it would work well. I'm hoping that Nest comes out with separate remote sensors that can be placed in areas that are frequented and will communicate with the thermostat so that I can use this feature in the future. This is a reallty cool device. Will it save me money? Maybe. I already used the capabilities of my last thermostat to it's fullest, so maybe not. But thats ok, I'm a gadget freak and this thing is way cool. My two concerns: WiFi can be hit or miss, that's why I have most of my devices hard wired to the router in my house. hard wiring is more robust. There are times it may go out, but the thermostat will keep working based on your programmed schedule till you connect back up. The other concern that several have mentioned here is charging the battery. My understanding is that the battery is charged when the system runs. If it's idle for a long time and needs to get juice, it will cycle your system to draw power. Some systems are sensitive and this may be a problem.If you have this issue, there are a couple of ways around this...you can remove the thermostat and charge it using the USB connector on the back. Not the most convenient, but an option. The other is to use a C wire if you have one, or if not, you may have a spare in the bundle in the wall that can be hooked up to the furnace and the Nest. If none are available, adding a C wire can be done, but could be a real pain for DIY. You may have to pay an HVAC technician for this. So far, enjoying the nest!
Pros Superb design, self-learning, intuitive settings, easy operation, full remote control.
Cons Kit should include anchors for dry-wall installation.
Summary Form and function are combined here to make a superb thermostat. My favorite feature is being able to remotely control the device. Just imagine: I could lure burglars to my home, then fry'em or freeze'em from miles away!
