When looking for an efficient Ultrabook, consider the Lenovo Thinkpad T430u 3351-8EU 14" Ultrabook Computer in black. Complimenting the performance of a dual core Intel Core i5-3317U processor with hyperthreading capabilities, 4GB of DDR3 1600 MHz RAM and a combo 500GB HDD / 24GB SSD is a compact form factor that measures only 0.83" in height when closed and just over 4 pounds in weight.
Powered by an integrated Intel HD Graphics 4000 graphics processor, the 14" anti-glare LED-backlit widescreen display offers HD viewing at 1366 x 768 native resolution and a cinematic 16:9 aspect ratio. The 200 nits of brightness and 500:1 contrast ratio makes for solid multimedia viewing.
Other Ultrabook amenities include USB 3.0 ports, mini DisplayPort and HDMI outputs, and an integrated webcam with HD720p resolution, wide angle views, low light sensitivity, face tracking and fixed focus capabilities. There is no optical drive, but it does include a 4-in-1 card reader with MMC, SD, SDHC and SDXC support for extra storage. The ThinkPad T430u 3351-8EU also includes integrated 4W (2x 2W) stereo speakers with Dolby Home Theater v4 technology, Realtek ALC3202 codecs and a built-in dual array microphone.
For networking, you have the option of the Realtek RTL8111F Gigabit Network Connection for a hardwired 10/100/1000Mbps connection, or the 802.11 a/b/g/n Wi-Fi running off the ThinkPad PCIe Half Mini Card, which also includes Bluetooth 4.0 support. There's an optional upgrade to advance to PCIe WWAN for a larger area of wireless coverage.
Add a 3-cell integrated Lithium Polymer battery with over 7 hours of runtime per charge and you're ready to go with a lightweight, portable and reliable Ultrabook. It comes preloaded with the Windows 7 Pro (64-bit) operating system, but a free upgrade to Windows 8 is included.
