I am disappointed by the Onyx Boox Max I just bought. It appears to not have undergone serious usability design or quality control.
The
single core processor runs from slow (PDF opening, navigation) to unbearably slow when it waits for all graphic rendering to occur instead of buffering (browser, email, on-screen keyboard). Rendering quality is barely acceptable, with various aberrations due to menu ghosting and poor dithering algorithms. Errors are often not reported and the affected functions simply do not work. The English manual is hard to read as it is not translated by a mother-tongue. The physical design is stupid: the power button protrudes from the bottom and is pressed when the device sits vertically. Build quality is weak: after one trip in a backpack, the case of mine formed a big bump on the back and now it wobbles when resting on a flat surface. Resting the pen horizontally on the screen causes writing to be registered. Pen precision is low compared to ordinary Wacom tables. The factory battery charge lasted only a day of sustained use. I have not yet found a way to lock the screen with a pin code, so note-taking is limited to public data.
