Motorola demonstrated a tablet device running on a Verizon Wireless LTE test network that could debut in the fourth quarter, though its actual market release likely will depend on Verizon's LTE deployment schedule. The demonstration, made at the Consumer Electronics Show, was one of several high-profile devices that have been shown off at the gadget trade show this week in Las Vegas. Samsung too was demonstrating prototype LTE devices at the event, including a media player, digital picture frame and camera. Article
