has announced that it expects worldwide combined tablet sales, lead by Apple's iPad, to outsell combined notebook sales
in 2013 for the first time ever. It also says that smaller tablets -- again led by the iPad mini -- will become the dominant size this year, a fairly obvious conclusion given sales over the holidays. The company says 7-to-8-inch tablets should account for about 45 percent of all tablet shipments, while the 9.7-inch full-size iPad and its competitors will slip to 41 percent of shipments. Overall, tablets will sell about 240 million units compared to notebooks' 207 million, a rise of about 64 percent year-over-year.
