Conclusion: With its swanky metal shell, good Webcam and sound system, and Lenovo's value-added performance and security features, the IdeaPad U400 is on its way to being a nice laptop. But our test unit gave us the impression that it wasn't quite finished yet.
Pros: Great Webcam and sound system, Strong performance, Gorgeous polished-aluminum case
Cons: Finicky touch pad, No perceptible processing boost from discrete graphics, Small, cramped keyboard
Conclusion: The Lenovo IdeaPad U400 brings the new U series stylish look and aluminum unibody design to a more mainstream size. But it's still one of the thinner and lighter 14" laptops on the market, and the U400 plus its smaller and light charger are easy to take anywhere.
Pros: Stylish unibody design, mainstream performance plus optical drive.
Cons: Battery is sealed inside, no matte display or Blu-ray options.
Summary: For better and worse--mostly worse--the Lenovo IdeaPad U400 is simply a larger version of its U300s Ultrabook . While we like its styling and larger hard drive, we still had trouble with its touchpad, and can't get over the fact that there's no SD card slot.
