The Yoga Book certainly has things going for it: At $500/£430 for its Android version and $550/£510 for Windows, it's cheaper than the baseline iPad Pro and the Surface 3. Having a scribing tablet directly integrated will likely appeal to an artistic demographic more comfortable drawing on a Wacom-style pad than directly on the screen with an Apple Pencil. It even records your stylus sketches when the tablet is asleep, which should boost battery life at the expense of, well, not seeing what you're writing or drawing.

But at the end of the day, the Yoga Book doesn't have a keyboard. Despite haptic feedback in the pad and autocorrect in the Android version, our reviewer struggled to type accurately, and doubted Lenovo's claim that it would take about two hours to adapt. If a user's work depends on quickly and accurately getting words on a page, this might not be the tablet for them. Lenovo is betting big that the physical process of pen-to-pad has secretly been what many tablet users have secretly been missing. We'll see whether it's enough to carve market share away from Apple and Microsoft.
