At a press event in New York today, Lenovo joked that it was the second largest PC maker that nobody's heard of, even after overtaking the silver medal from Dell in October and eyeing HP's lead. It's true, most people have no clue who Lenovo is. Some people might know that IBM sold its PC division to the Chinese company in 2005, but Lenovo's PCs and tablets can hardly be considered breakthrough or iconic. Meet the IdeaPad Yoga. Is it an Ultrabook? A giant 13.3-inch tablet? An oversized tabletop digital calendar? It's all of those and it's one of the most interesting transforming laptops we've seen in a while.

Somebody want to tell me how Samsung's new Series 5 laptop got Intel's "Ultrabook" stamp of approval? The new 14-inch laptop is still thin at 20.9mm and somehow manages to cram an optical disc drive into its side, but it's already breaking the definition of "Ultrabook."
