Sales of the iPad could reach 6 million by the end of 2010, and 7 million within the first 12 months, says Morgan Stanley analyst Katy Huberty. The figure is based on a new survey of 2,500 people, of whom 21 percent say they are interested in buying an iPad. 4.6 percent have expressed "extreme interest" in buying an iPad, while 16.4 percent say they are "somewhat interested."
