I saw the new(?) »www.homedepot.com/h_d1/N-5yc1v/R···X-03A9gA WiFi Honeywell yesterday in Home Depot also. The box was very vague but it does not seem to do a 2 stage heat pump with aux heat.
The Honeywell specs seem similar to the RadioThermostat 3M50 unit which I have on several single stage systems. -- The difference between genius and stupidity is that genius has its limits.
The Honeywell looks very functional but at 10" square, it breaks my "Jupiter 2" rule regarding the prominence of technology. I prefer to not have consoles and command centers on display. After all I'm just trying to enjoy my home, I'm not navigating through space. At under 3.5" the Nest even beats out the classic Honeywell button on the wall that HD is selling.
