Best Buy is hoping to jump on the tablet bandwagon with a device of its own, the company's CTO Robert Stephens has teased. The design is an empty shell at present but when finished would carry the Rocketfish badge applied to many of its in-house computer peripherals. Stephens had previously said that a future tablet would use Android 2.2, and in shots showed that the tablet would be smaller than the iPad it's targeted against.
