Windows 10 would seem to be the more natural choice then, but that’d put more stress on the Yoga Book’s mediocre specs. The device runs on a 2.4GHz Intel Atom X5 processor and 4GB of RAM. It’s enough to do simple web browsing and video viewing without too much delay, but even on Android, it’s never outright fast, and definitely not where a $500 tablet should be.

Benchmark tests put it on the level of a flagship phone from 2014, in fact. Modern mobile games like “Lara Croft Go” consistently stuttered whenever things intensified onscreen. Don’t count on Photoshop running with aplomb, either.

As you might expect from a device this thin, there isn’t much in the way of connectivity. You get a microSD slot to expand on the 64GB of base storage, a micro-HDMI port, and a headphone jack. Disappointingly, Lenovo’s also opted for an increasingly outdated microUSB port instead of the faster and more versatile USB-C.

In any case, you have to get used to that all-touch keyboard. For what it is, it’s good. It doesn't lag, it smartly uses haptic feedback to let you know when your presses register, and it’s much faster than using the onscreen alternative.

Still, that’s all relative. It’s cramped, for one — I constantly had to look down to hit character and function keys, which slows the whole process up. It has trouble recognizing presses from fingernails, too, and pressing against a harder surface for an extended period of time can fatigue your fingertips. Everything is tolerable, but it won’t stop you from reaching for your laptop when it comes time to get real work done.

Less tolerable is its accompanying touchpad, which is maddeningly hypersensitive. Any time my palms brushed up against it while typing, it’d send the onscreen cursor wildly flying about. Again, this is a 10-inch device. I’d usually contort my hands just to avoid touching it. Its multi-touch support is rough, too — things like pinch-to-zoom or fast scrolling are either not there or incredibly finicky. You can do the basics, but that’s it.
