I might. David Pogue describes it, including this:
RADICAL CHANGE 1 The look. The Nest is gorgeous. It’s round. Its screen is slightly domed glass; its barrel has a mirror finish that reflects your wall. Its color screen glows orange when it’s heating, blue when it’s cooling; it turns on when you approach it, and discreetly goes dark when nobody’s nearby.
Sweating over attractiveness makes sense; after all, this is an object you mount on your wall at eye level. A thermostat should be one of the most beautiful items on your wall, not the ugliest.
RADICAL CHANGE 2 The Nest has Wi-Fi, so it’s online. It can download software updates. You can program it on a Web site.
You can also use a free iPhone or Android app, from anywhere you happen to be, to see the current temperature and change it — to warm up the house before you arrive, for example. . . .
