On the face of it, the Yoga Book is very similar to Microsoft’s Surface-range of productivity tablets. Similar to Apple’s iPad Pro and Samsung’s Galaxy TabPro S. Similar to Huawei’s MateBook and Asus’ Transformer 3 Pro. No matter how big the list, however, the Surface will invariably lead the way. It is after-all a category defining product. It is after-all the Optimus Prime of convertibles. Lenovo couldn’t agree more. The Yoga Book may work on a similar concept, but its ambitions lie elsewhere. Unlike the iPad Pro, the Galaxy TabPro S, the MateBook and the Transformer 3 Pro, the Yoga Book isn’t looking to kill the Surface. Heck, it isn’t looking to kill anybody. It’s looking to create a new category altogether.
