I'll ignore the snarkiness of this comment. There aren't any other 13.3 inch e ink readers out there that run on the latest version of Android. Furthermore, Onyx have announced upgrades are coming for the Boox Max. Also, Android support contrasts this device to say the Kindle DX which you can't use with your favourite reading apps etc.
