In the last Home Depot flyer here in Canada there is a new Honeywell wifi internet connected unit for $160. I saw it last night and it looks like any other Honeywell unit but has the wifi signal indicator bars on the screen. I havent seen it elsewhere.
It would do everything the Nest would do for me, as my thermostat is somewhere where someone might walk by it to trigger its motion sensor once a week.
I looked everywhere on the internet and nest sure tries to make the web interface and any actual screen shots or description of what the software will do a secret. I guess they just want to let their built in program rule the day. Just like apple.
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.
