Lenovo's Yoga 720 brings a bit of game with discrete GTX 1050 graphics

The 15.6-inch IPS display has a resolution of up to 4K Ultra HD (3840x2160). While that incredible crispness is tempting, you may not want to run it on that resolution all the time, as it uses more battery life. Lenovo estimates the Yoga 720 will last up to 8 hours at UHD, but up to 9 hours if you drop to FHD (1920x1080). 

Connectivity stays on trend with USB 3.1 Type C and Thunderbolt (using the Intel controller). You also get active pen support and a fingerprint reader for easy Windows 10 authentication. In an early briefing, Lenovo told us that product managers consciously chose that mode of authentication because users were familiar with it through smartphone use. It’s also cheaper and easier to integrate a fingerprint reader than to shoehorn Intel’s RealSense camera (for facial recognition) into a slim-bezeled unit. 

Of course, the Yoga 720 also offers the fun of using the laptop in clamshell, tent, or view modes simply by rotating its two halves around its 360-degree hinge. I wouldn’t recommend using this 4.4-pound machine as a tablet unless you could rest it on a table or your lap, but it’s a very nice option to have, especially in cramped quarters such as a commuter train or airplane. As the flagship Yoga product, the 720 promises great flexibliity, and now, with the discrete graphics option, great power
