While wearable devices may still feel like the stuff of science fiction, they are very much a reality — as evidenced by the Samsung Galaxy Gear Smartwatch ($300). This watch does so much more than simply tell time, thanks to its ability to pair with any Samsung Galaxy device. For example, it will discreetly notify you of a new text message, let you preview its contents, and then instantly open it on your larger device. Other powerful features include the ability to interact with music, letting you browse, pause, play, skip, or adjust volume. A built-in microphone, bluetooth connectivity, a video and still camera, an accelerometer, a gyroscope, and a pedometer further extend the usefulness of this handy watch. Available in October.
