Nest has an awesome feature called AirWave.

When you're running the AC, it actually learns how long it can continue to cool by just running the fan due the the lingering coolness of the coils after the compressor has been running. This causes the AC compressor to run less while you're still able to be kept cool, at significant cost savings.

Your standard thermostats currently don't do this.
