The guys at Pocket-lint sound pretty certain that this device is to be unveiled at the Computex show in Taipei, Taiwan on May 31. According to their info (and it seems they have also obtained a render of the tablet), the ViewSonic ViewPad 7x will be powered by a dual-core Tegra processor, will sport two cameras, HSPA+ support and a few connectivity options. DLNA and HDMI connections will also be on board. It's said its weight is 13.4 oz.
As of now, it's unknown whether it will be launched with Honeycomb 3.0 or the newly released Honeycomb 3.1. According to the rumor, the ViewSonic ViewPad 7x is to be launched in June, but there is no information about its price.
