Introduced in early August 2008, the B-Series is a new series of inexpensive media players from Sony. With capacities of 1 and 2GB the B-Series includes a fairly wide variety of features such as voice recording and FM radio/recording. With 16 hours of continuous audio playback, its battery life is not as impressive as the E or S-Series, but it still compares to the competition favorably in this regard. Cost is $45 and $60 for the two different capacities, comes in black, pink, and red (blue is also available for the 1gb model).
