Lenovo is back with another twisting laptop, and this time, it can twist itself. Today at IFA, the company showed off its Auto Twist AI PC concept, which has a motorized hinge. It can track your movements and rotate its display to face you as you walk around it and can transform itself into different modes in response to voice commands. The Verge’s Jennifer Pattison Tuohy got a hands-on — well, hands-off — demonstration.
