Lenovo is preparing to introduce a new ultraportable notebook, the ThinkPad X220. Although a product page isn't up yet, the system's Lenovo notes other business-friendly features, such as a quiet keyboard, microphone and speaker mute buttons with LED indicators, a 720p webcam, as well as the ability to adjust the mic's sensitivity for a single person or conference calls. There's also a new buttonless touchpad that we've found pretty finicky, but we'll reserve final judgment for our upcoming review.
