Lenovo's IFA itinerary is marathon-length. It unveiled no fewer than three tablets yesterday, not to mention three new IdeaPad S Series notebooks, and today it's serving up more laptops. Let's hit the high-profile guy first: Lenovo's IdeaPad Series lineup of Ultrabooks is getting its first 15-inch model, the Windows 8-running U510. The machine weighs 4.85 pounds (2.2kg) and measures 0.83 inches (21mm) thin, which is hefty for an Ultrabook but gives it enough room for a DVD burner or an optional Blu-ray drive. The 15.6-inch display's resolution is a ho-hum 1,366 x 768, which is exactly what you'll find on the IdeaPad U310. The laptop will be available with up to a Core i7 Ivy Bridge CPU
