Apples and oranges really. If you just want a 10′ tablet go with the Chuwi. The Yoga Book comes with pen support, a keyboard (even if it’s touch based much better than the onscreen ones) all included in the price. Wait for reviews on both though since the cherry trail tends to overheat if the cooling solution implemented by the manufacturer is sub par.
Personally I will probably go with the Yoga. For tablet only I would pick the Mi Pad2 windows version.
