Here is a review on the Lenovo Yoga Book, the first-ever super unique convertible laptop.
Yoga Book comes in two versions, one for Android Marshmallow ($499.99), one for Windows 10 ($549.99).
The Design
When it's closed, the Yoga Book looks like those expensive Moleskine notebooks. The black magnesium-aluminum body is silky to the touch with just a hint of graininess. A glistening chrome Lenovo logo is installed in the bottom left corner of the cover, emphasizing the silvery aluminum watchband hinge that's become synonymous with Lenovo's Yoga series convertibles.
The backlit "Halo" keyboard on Yoga Book, as Lenovo calls it, includes no shifting parts and appears, only when you need it, as a white outline that's not quite a hologram on top of a panel that is below and separate from another panel where you see the Full HD touch display. In other words, this is not an onscreen touch keyboard, but rather one that is supposed to let you more naturally type as if you were using a regular Qwerty keyboard on a laptop. But this type, you don't need to push a specific letter, for example, just to type it and see it on screen. Instead, you just have to touch it.
Meanwhile, the nonexistence of any physical keys on the Halo keyboard means Yoga Book can fold into an extremely slender close like on a shell. The Yoga Book is impossibly slim and light at 1.5 pounds, 10.1 x 6.7 x 0.38 inches.
The Display
According to Sherri Smith, writer on Tom's Guide, the Yoga Book's 1920 x 1200 IPS touch display is bright and colorful, but the hues could be more accurate. The Yoga Book's panel reproduced 101 percent of the sRGB gamut, which is excellent. It defeated the 95-percent ultraportable average as well as the 99, 84 and 56 percent result put up by, respectively, the Surface 3, the Miix 310 and the Inspiron 11 3000.
However, the color accuracy left much to be desired, as the Yoga Book hit 5.2 on the Delta-E test, far beyond the 0 ideal and the 2.1 average. The Inspiron 11 3000 and the Surface 3 were better at 3.8 and 3.1, respectively, but the Miix 310 proved the most accurate at 0.8.
