Lenovo contributed a third model to its tablet introductions early Wednesday with a lone Intel model. The 10-inch IdeaPad P1 will be one of the last Windows 7 tablets and support both finger-touch and an optional pen. It carries an unnamed 1.5GHz Intel chip (likely an Atom Z670) and will be slightly bulkier than Android models at 0.57 inches thick and a weight just under two pounds.
