The Lenovo 13-inch Yoga Book 9 is variation on the convertible laptop idea. Instead of a conventional keyboard, it has a second 13.3-inch screen that you can use as an additional display or as a virtual keyboard. You can also use it with the supplied Bluetooth keyboard to work in laptop mode, with it propped up in front of you to see both screens. But novel design aside, is it actually any good? Find out how this innovative Lenovo laptop fared in our tests by reading our full review.
