After wowing us at CES with the Xperia Z, Sony enticed us at Mobile World Congress with the Xperia Tablet Z. Both devices combine top-notch specs with beautiful industrial design -- pure rectangular forms with a mirror-like finish packaged in thin, light and water-resistant shells. We sat down with product marketing manager Stephen Sneeden in Barcelona to talk about these iconic products. We discussed the "omni-balance" design and the common user experience shared by both devices, which was spearheaded when Kuni Suzuki became Sony Mobile's president and CEO. He explained that some of these design elements will likely be incorporated into future (non-mobile) products and that the both the Xperia Z and Tablet Z are premium, aspirational devices which will become reference points for more affordable models. We then chatted about the Tablet Z's specs, in particular its impressive thickness (6.9mm / 0.27 inches) and best-in-class weight (495g / 0.99lbs). Mr. Sneeden mentioned the TV SideView app, an electronic programming guide with voice activation that's available from the Play Store and takes advantage of the Tablet Z's built-in IR blaster -- he also pointed out that Sony's Music Unlimited and Walkman Player apps will be fully integrated by summer. We touched upon a few other topics, including the Xperia Play and PlayStation Certified program for phones. Check out the full video interview after the break.
