IdeaPad 300s - The First Ultrabook for Consumers

Lenovo's U300s Ultrabook features 13.3" screen with 1366*768 resolution ans is powered by Intel Core i-series "Sandy Bridge" processor, up to 4GB of DDR3 memory, up to 256GB solid-state drive, Bluetooth, Wi-Fi 802.11n, USB 2.0 and USB 3.0 connectors, as well as an integrated 1.3MP (720p HD) webcam and so on.

Other smart technologies include the so-called breathable keyboard, Lenovo enhanced experience 2.0, an Intel advanced cooling technology that allows air to flow in through the keyboard and out of the sides and rear hinge. This design removes the need for vents on the underside of the notebook, which allows usage for long periods of use on laps or even on a pillow.
