Nice interview with Nest Co-Founder Matt Rogers by Kevin Rose: http://9to5mac.com/2012/10/02/nest-co-fo...ew-nest-launch/

You can listen to most of it in the background without watching the video.

Not related to the video, but another caveat with regards to humidification is that Nest doesn't have any external/remote thermometer to monitor the temperature outside your house. Internet weather forecasting isn't a suitable replacement for real-time measurement when you're controlling a humidifier trying to avoid dew-point issues like condensation. It seems like their humidifier control is mostly suited to the most simple manual units. Mine comes with its own automatic controller which monitors outside temperature and frequently samples the humidity of the return air duct - it's also able to humidify without the HVAC already running a heating cycle, by turning on the fan itself.
