When buying a lightweight laptop, you often have to choose between functionality and portability, sacrificing amenities to save space. Built for business but user-friendly enough for anyone, Lenovo's 12.5-inch ThinkPad X250 offers a full HD display, a snappy keyboard, epic battery life and a complete suite of ports in a durable chassis you can take anywhere. You can find laptops that are a bit thinner or lighter, but Lenovo's long-lasting ultraportable is great for serious work, and lets you leave your dongles and power brick at home.
