The Chuwi Hi12, which I regard as one of the best dual boot tablets for the price, has quietly been upgraded to the newer revised Atom X5 Z8350 processor, no doubt due to the fact Chuwi simply just ran out of the old Z8300 stock. The newer Z8350 isn’t worth upgrading to if you own the Z8300 model as it’s only a tiny bit faster. Why this Hi12 is one of the best dual OS models is due to the combination of the largest battery (11,000mAh) seen in a dual boot, the Surface Pro 3 screen it uses with a sharp 2160 x 1440 resolution & stylus support. Two full sized USB ports, which even Chuwi has done away with on the new Hi13 (everyone is switching to just type-c ports) And one of my favorites is its stock launcher and bloat-free Android ROM. Not to mention the newer keyboard dock is much better than the old one and give use two more USB ports and it works like a transformer stylus keyboard.
The price has also been dropped to $235, at least over on Banggood.
