The Yoga 900 keeps the same general look as its predecessor, with an aluminum case in silver or orange and a hinge that looks like the links of a watch. This year's model is a little thinner and lighter, though: It's 0.59 inches thick and weighs 2.8 pounds.
That makes it a good choice for people who want a premium laptop that also works well as a tablet. The Surface Book is even better in that regard, with a great detachable screen and pen support, but it's also heavier and more expensive.
In terms of performance, the Yoga 900 is on par with other thin and light machines we've tested this year. In our OpenOffice test, it took just 4 minutes and 18 seconds to match 20,000 names and addresses, making it slightly faster than the Inspiron 13 7000 (4:32) and 40 seconds quicker than the Spectre X360 (5:04).
The Yoga's pixel-dense 3200x1800 13.3-inch display is also a standout. It's super-sharp, and it did a terrific job of displaying photos and movies in all of our tests. We especially liked how the colors looked in the trailer for Quentin Tarantino's The Hateful Eight, which showed off the rich goldenrod lapels on Samuel L Jackson's suit.
The 900 has a few preloaded Lenovo tools and utilities, but otherwise it comes with the standard Windows 10 software package. That includes Microsoft's digital assistant Cortana, the Edge web browser and built-in mode detection that automatically switches between laptop and tablet views depending on the position of the keyboard. It also has REACHit, which adds voice command support for search across cloud services besides OneDrive.
