Lenovo Yoga Book C930 (i5-7Y54, LTE, E-Ink) Convertible Review

3-in-1 convertible. The new Yoga Book has an E-Ink display instead of a keyboard and is considered a combination of a laptop, a tablet and an e-reader. On top of that, you can also digitalize text and drawings with this allrounder. The device is based on its predecessor from 2016 but offers many changes and improvements. For example, it provides better performance. On the other hand, it has also dropped at least one feature. Is the 2018 Yoga Book worth twice the price of the old version? Find out in our detailed review App Store.

The first Lenovo Yoga Book was published in 2016 and attracted its unique feature with its unique features: a keyboard, instead of 360-degree convertible, with a touch surface that covers the base unit. This can be used as a virtual keyboard or as a drawing board on which users can print a piece of paper and notes or draw with the pen included. The inputs will then be digitized Alienware 17 R5 review: Full, in-depth review.

The new Lenovo Yoga Book C930 – not to be confusing with the Lenovo Yoga C930 (without the “Book”) – has reinvented itself. Instead of the touch surface, we are now treated with a second screen – an E-Ink display with 1080p resolution. The paper holder has been removed. Instead, the E-Ink display can be used for typing, drawing, writing, and even as an energy-efficient e-reader.

We at Notebook check encountered a very special problem: This very special device is so unique that it can be hardly compared with any other notebook, tablet or convertible. So, we chose both convertibles and tablets as our comparison devices. These include the Microsoft Surface Pro (2017), equipped with a little weaker m3 processor (also an alternative for the Yoga Book), the Huawei Matebook E and the Lenovo ThinkPad X1 Tablet Gen with the same CPU. Of course, we also compared today’s test unit with its predecessor.

The only real weaknesses of the first Yoga book were the small portfolio as well as the slow eMMC storage. At least the latter has now been replaced by NVMe SSD. We will discuss any other differences and whether the Yoga Book can be reviewed in this review.

We want to highlight another difference: The price. While the most expensive version of the preecessor costs around $ 600, Lenovo now charges $ 1050 for its Yoga Book. We would expect a lot of useful improvements and changes for this drastic increase in price. Currently, there is only one version available in the US. It is equipped with a Core i5 processor and a 128-GB SSD.
