The ThinkPad X220 12.5" Laptop Computer from Lenovo is a thin and light notebook computer with a 12.5" LED backlit widescreen display. The system weighs only 3.3 pounds and can operate for up to 9.2 hours on a single battery charge, making it an ideal system for all-day on-the-go computing. It features a comfortable keyboard and Lenovo's UltraNav system for mousing. UltraNav combines a TrackPoint and a large multi-gesture TouchPad for precise cursor control.
The ThinkPad ships with Lenovo's Ultrabase Series 3 dock. The dock, designed to be used when you are using the notebook at your desk, features DisplayPort and VGA video output, four USB 2.0 ports, a Gigabit Ethernet port, audio input and output ports, and a DVD burner. It makes it easy to convert your compact notebook into a desktop workstation -- just leave an external monitor, keyboard, and mouse connected to the dock for quick access!
