Lenovo makes a lot of Microsoft Windows-based convertible computing devices, but we now have something rather unique. It is called the Yoga Book, and it really is a one-of-its-kind product. At first glance, it looks more like a spiral notebook; it’s 9.6mm thick. Open it up, and you will realize how thin and compact it is. The display hinge design is similar to the one in the much more expensive X1 Carbon laptop. The build quality of the metal chassis is good and the featherweight design, useful.
But the real visual highlight comes when you open the Yoga Book. You’ll probably wonder where the keyboard is. The Halo keyboard is touch-sensitive, the keys are illuminated when you need to use them, and the surface can be used to scribble with the stylus. If our experience is any indication, it certainly takes time to get used to this—our fingers are not really ready for a touch-screen laptop keyboard, so you will stumble till muscle memory kicks in.
Lenovo has tried something unique, but we aren’t entirely sure if people who need to write a lot will be impressed. Second, we also noticed that the touch pad is a tad erratic, either not registering a swipe gesture, or sometimes haphazardly opening apps you didn’t need at the time.
The Yoga Book isn’t exactly what you’d call quick, because the Intel Atom x5-Z8550 processor, paired with 4 GB of RAM, has its limitations. It can handle some amount of multitasking, but open more than half-a-dozen Chrome tabs with heavy visual elements, and the sluggishness becomes apparent. While HD media playback is smooth for the most part, there will be the occasional stutters if the video file is running a complex video codec.
The Yoga Book is preloaded with Windows 10 and has 64 GB flash storage. There is a card slot that accepts 128 GB more storage space, in case you need to have more space available for documents and media content, and aren’t enthused about the idea of carrying a portable hard drive with you.
In terms of battery life, the Yoga Book easily lasts close to 11 hours when used for Web browsing and music playback. If you want to carry it with you for a day of meetings, you would perhaps be able to leave the charger at home.
The 10.1-inch IPS display has Full HD (1,920 x 1,080 pixels) resolution. The vibrant colours and good contrast make it ideal for entertainment. It’s sharp enough to make reading text on the small screen quite easy.
The clever keyboard and writing support make the Yoga Book a unique proposition in the computing device ecosystem. But there are limitations, such as the learning curve for the touch keyboard.
