We expect a 2.0 product to be deep with features, but the radio SHARK 2 lives on the surface. Digital video recorders radically changed the way people watch TV, so why not apply those tricks to radio? Griffin’s radio SHARK 2 is a USB AM/FM radio tuner that lets you record and play radio content on your Mac. As DVRs do with video, the radio SHARK 2 buffers the audio so you can rewind and pause live shows. But it lacks other important features, such as solid Internet radio integration and dual tuners.
