Panasonic has just revealed the Viera tablet at its CES 2011 press conference. What we know so far is that it's Android based and will be available in 4, 7, and 10-inch sizes. Besides the difference in screen size, each of the tablets will feature identical hardware. Panasonic is positioning the device mainly as a TV companion. Using a feature called Viera Connect, tablet owners will have the flexibility to transfer content between the tablet and TV -- or even view the same content simultaneously from different angles. The tablet will also function as a remote for controlling home theater components and content. Pricing in the US is unlikely to be announced in the near term, but further details related to its Japan launch will be revealed later today. Check out more images of the device in the gallery below.
