The best things to do with competition are to know them and to respect them.
Here's what our competition is, sort of:
Go read the Honeywell Touchscreen Thermostat and Portable Remote Review and keep in mind that there is a subtle distinction between Prestige HD and Prestige SD (about a hundred dollars or so).
Then go do some shopping (zoning system not included) and hopefully come back - if not today, then in a few weeks or months when the GUI (and other unannounced bells and whistles) is back to its former glory and beyond, for the price of Prestige with comparable feature set is steep indeed.
By the way, DZ is going to look nothing like Prestige :)
UPDATE:Favorite quote from the Homeowner Brochure (emphasis mine):
This is what it looks like. This is what it looks like :)
You can even name each of your zones on the Portable Comfort Control by having your contractor customize it with more than 60 different naming options - upstairs, master bedroom, office - even wine cellar and home theater!(Image Credit: Gizmodo.com)
