Lenovo Thinkpad X1 hands-on: A meatier, more useful update

This CES, the company has more substantial changes to reveal. The new Thinkpad X1 series now come with microSIM card slots and e-SIM technology, so they'll remain "always on, always connected," per Microsoft's marketing language. The X1 Carbon laptop and X1 Yoga convertible are also the first PCs announced to sport screens with Dolby's Vision HDR technology, and feature built-in privacy shutters for the webcam. All three X1s are also equipped with twin far-field microphones that can hear you from up to four meters (about 13 feet) away, so you can shout at Cortana from across the room if you wish. At my demo here in Vegas, the Thinkpad X1 Yoga was able to hear me and Lenovo's reps from at least 12 feet away.
