Add: 7/2 finally, an unbiased review of Nest: http://o.canada.com/2012/06/26/nest-learning-thermostat-review/ (it doesn't work)
Thermostats: hysteria or hysteresis?
Despite all of the input which is posted at Home Energy Pros and elsewhere, right now there are only two thermostat brands that matter, legally speaking: Nest, and Honeywell.
First, Honeywell sued Nest for patent infringement.
Second, Nest filed its counter claims to Honeywell's suit.
Now, Honeywell has just filed 20 pages of its opinions about Nest's counter-claims, and denies Nest's allegations.
It will all be decided in court over the next three years. In the meantime(6/5/12), the Nest has been added to the Apple store.
6/23/12 CR(consumerreports) is testing the Nest along with a bunch of others, last time Lux was the big winner).
