The coolest new gadgets of 2013

Key Player

Bid adieu to that stomach-sinking "Did I lock the house?" feeling, or the not much better "I locked myself out—again" moment. Lockitron provides keyless lock and entry initiated through a Smartphone app. For added peace of mind, those with kids can also receive texts when they arrive home.

Climate Control

An energy-efficient thermostat may not seem like the most cutting-edge technology, but this one deserves a warm welcome. The Nest thermostat allows you to control your home's temperature remotely from your smartphone. Once it learns your routine and preferences, it will adjust the temperature throughout the day and lower your energy bills too (by up to 20 percent).

Hot Stuff

Smoothing down your locks shouldn't require major heat. The makers of the Coolway Autosense Styler have developed technology that senses the moisture levels in hair and then lowers the temperature of the iron accordingly. The result? Sleek, smooth hair without the risk of heat damage.

Time Will Tell

The Pebble is the first "smart" watch to offer full iOS and Android compatibility with its Bluetooth capabilities. This customizable gadget can act as a distance-tracker and mp3 player, while keeping you updated on Twitter, Facebook, Instagram and on and on and on… (because we all know how obsessed we are with social media).

Now Hear This

Sometimes a great gadget is more about what you don't see than what you do. With Griffin Technology's Wireless Sound, you can stream sound to your existing speakers, from your iPhone or Air-Play-enabled apps (such as Pandora, Spotify, Rdio), all without a single wire in site. Rock on.
