When it comes to alarm clock docks, it's no longer enough to have good sound quality. Most systems now offer apps that provide increased functionality for your dock, such as Internet radio and weather forecasts. Gear4 is trying to stay ahead of the curve by adding a sleep monitor, which uses a radio transmitter to measure your body movement and breathing while you sleep, and lets you know how long you slept and how restful it was. But any alarm clock dock has to be able to wake you, and sound good doing it, too. So how does the $199 SleepClock stack up against the competition?
