The fastest ultraportable around:- When your need for speed and your need for mobility converge, look to the ThinkPad X220 to rise to the occasion. The same full-powered 2nd generation Intel Core processors that fuel many 14" and 15" laptops are built right into the X220's slim - it's 2mm thinner than previous generations - frame. Energize graphics-intense programs with two-times-faster Intel HD Graphics, and instantly increase your startup and shutdown times with Lenovo Enhanced Experience 2.0 for Windows 7, with optional RapidDrive. Intelligent design:- We went feather-light on the weight (starting at under three pounds), but we still loaded the X220 with heavy usability features. Type more comfortably and accurately with a 45 percent larger, buttonless touchpad design on our industry-leading Thinkpad keyboard. Rely on our premium durability standards and Active Protection System to provide a rock-solid machine, which now includes a redesigned hinge with stronger magnetic-latching support.
