Reviews for the Lenovo Yoga Book YB1-X91F

Lenovo Yoga Book Review
Source: Toptenreviews
The Lenovo Yoga Book is a bold move. It does point to a convertible concept of the future. The hinge and paper writing digitization trump the current competition, and a bigger Yoga Book might be even more attractive. With a 12″ screen there’s room for a correctly spaced keyboard and a bigger touchpad.
