The mStation 2.1 Stereo Orb is a one-piece speaker and docking system for iPods — and other devices. While it looks more or less like a colored bowling ball, it is actually a decent compact stereo system available in seven spiffy colors. Technically, there are two 2-inch front-facing drivers, a 3-inch rear-facing subwoofer, and a 30 watt power amplifier inside the Orb.
