Motorola chief Sanjay Jha in a presentation at Morgan Stanley's Technology, Media and Telecommunications Conference this morning detailed some of the company's plans to expand its tablets and its smartphones. He reiterated intentions to put out a seven-inch Android tablet before the end of 2011 but saw it as targeting a different market. The smaller size would be "fun," he said, where a 10-inch tablet like the Xoom was now being skewed more towards high-end users.
