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, up to 8GB of RAM and a 500GB, 750GB or 1TB hard drive and optional 24/32GB SSD cache. Connections include USB 2.0, USB 3.0, VGA and HDMI, and there's an SD card reader as well. Lenovo rates the machine for six hours of battery life. The U510 will set you back $679 (for the entry-level configuration) when it goes on sale in September. For now, you can check out our hands-on photos below.
