Lenovo's Yoga Book is a new kind of tablet. While it's similar to a two-in-one or convertible PC, the Yoga Book eschews a keyboard for a second touchscreen, although touch surface may be a more appropriate phrase.
This secondary black-and-white display can light up and become a software keyboard with haptic feedback. The lack of physical travel is a bit weird, but after you use the keyboard for long enough, it starts modify each key's "hit zone" to account for your mistakes.
If you pop a piece of paper over the touch surface, you're able to write or draw with a real pen on the paper while your is instantly digitised at the same time. Unlike other text digitisation solutions, there's no need for special paper or an extra sensor.
You also get a stylus in the box, which works with both the screen and touch surface.
The Yoga Book's screen and touch surface are joined with what Lenovo calls a "watchband hinge". Inspired by stainless steel watchbands, the hinge helps keep the tablet thin. When closed, the Yoga Book is just 9.6mm thick. The device weighs in at 690g.
Key specifications include a 10.1-inch Full HD display, Intel Atom xX-Z8550 quad-core processor clocked at 2.4GHz, 4GB of RAM, 64GB of storage (expandable via microSD), and a battery said to last up to 15 hours.
The Yoga Book is available running your choice of Android or Windows. The Android Yoga Book is on sale now, and is priced at $799. The Windows 10 powered take on the Yoga Book should be in stores early next year for $999.
