The Roku SoundBridge Radio WiFi music system ($400) is much more than just a clock radio. Besides receiving FM and AM broadcasts, it also has WiFi capability. If you have a wireless network, the SoundBridge radio can access music files on any Mac or PC connected to the network. It can also play Internet radio stations, waking you up in the morning with your choice of sound source and dual alarms, too. It does all that with tremendous sound quality. We took a listen, and here's our review.
