It's always fun to have the latest and greatest version of the gadgets we love, but sometimes the previous generation is nearly as good and a better overall value. Such may be the case with the new Nest Learning Thermostat.

The 3rd generation of the popular temperature controller was announced yesterday and boasts a few minor improvements over the now "old" 2nd generation Nest. The display is larger, it's a bit thinner, and sports a couple of new features and sensors. If you want to read the full breakdown of changes you can read Cameron's article about the product announcement here.

While the aesthetic changes and added features are nice, the Nest 2nd generation is still an incredibly capable device. It's also a better value as the price has dropped $50 to $199 now that a new Nest has entered the scene. You can pick one up for yourself at Amazon.

You might want to act rather quickly if you want to pick up the discounted Nest 2. With the new version now on the market it is possible the older model will sell out in the coming days. Once it is gone, I don't expect it will be restocked.

If the new look and features of the Nest 3 are worth a 50 dollar price bump, then you can purchase it here.

My wife and I bought our first home last month and I have been planning to buy a Nest for a long time. Now I have to decide which one I will get. Which one do you think I should buy? Or, is there another thermostat that I should consider? Let me know in the comments below.
