Every time all winter my wife asks me to get out of bed to go downstairs to change the thermostat that's awkward to use and hard to see in the available light, you can bet I'm going to be thinking about how I could have a Nest and just adjust it from bed using my phone. Combine that with plausible claims of it saving us $100+ a year in energy bills, and this is a very appealing product, IMO.

I think the "problem" he's referring to is the learning aspect. Web based thermostats and home automation have been around for over 10 years.
