Finally, though not technically a part of Lenovo's Yoga line, the company's "Flex" laptops have also received an update. In particular, whereas they used to only be able to bend part of the way back, they now have the same 360-degree hinge as the Yogas, allowing them to be used in all four modes (Notebook, Tablet, Stand and Tent). In total, the lineup includes three models in 11-, 14- and 15-inch sizes, with the bigger two offering optional 1080p displays, fifth-gen Intel Core i5/i7 processors, and a choice between integrated and discrete graphics. (The 11-inch model runs on a lower-power Pentium CPU.) So in many respects, these basically are Yogas, except for one thing: The build quality isn't quite as nice. Also, they're heavier, at 3.08 pounds, 4.29 pounds and 5.07 pounds, respectively. The new Flex laptops go on sale in May, starting at $399 for the 11, $549 for the 14, and $579 for the 15.
