Regularly available for less than $750, this thin, 3-pound convertible is a solid choice for anyone who needs a laptop for office or schoolwork. The all-metal chassis gives it a premium look and feel, and it has a comfortable keyboard and responsive, smooth precision touchpad. Though it's light on extra features compared to its premium linemate, the C940, it does have one of Lenovo's sliding shutters for its webcam that gives you privacy when you want it. And it has a long battery life to boot.
