The Lenovo Yoga C640 is a great device for middle and upper management users who are on the move always. For these users the 1.35kg weight of this laptop will be a huge advantage, along with the tablet mode that makes it easy to consume content on the move. And there is literally nothing you can’t do with this device, though the 13.3-inch form factor does not make this a device that can be suggested as a desktop replacement. The convertible aspect makes this good for those who need to teach or present stuff all the time.

Despite its middling keyboard, lazy touchpad, sub-par audio, and heavy price tag, the Lenovo Yoga C640 emerges as a satisfactory choice for buyers who want a thin and light convertible laptop with good performance, bundled stylus, and a really long battery life.

So, in the first place, we would want to mention that this laptop feels like a gap-feeling notebook. Somewhere between the Yoga 500 and Yoga 700 series. However, when we got some time with it, and of course, didn’t take into consideration the aforementioned, the Yoga C640 (13) actually does a pretty fine job. And has a great keyboard too.
