There may not be an Apple iWatch this holiday season, but Samsung has entered the smartwatch race and is currently selling its Galaxy Gear device, which is compatible only with its Galaxy smartphones.
Its smartwatch can make and receive calls and take pictures. It also has a voice control function.
It runs its own apps and is wirelessly connected to a Galaxy user's smartphone so that it can show a user's updates, like email or texts, on the smartwatch screen. It also has built-in sensors so that it can double as an activity tracker.
