Apple seems to be a big fan of the Nest learning thermostat. So much of a fan, in fact, that it's decided to start selling it in its physical and online stores.

In many ways, it's not a huge surprise: Nest is the brainchild of Tony Fadell, an ex-Apple engineer, and it shares an emphasis on usability and design that's common across all of Apple's products. There's also deep iOS integration built into the thermostat, which costs $250.

It is, however, somewhat of a departure from Apple's usual product range. What next, domestic appliances? [Apple]
