Web browsing on e-ink is widely known to be barely usable, and not what e-readers are made to do. So usage of "even" word is hard to explain here really.
I admitted I didn't have any experience using e-readers before, so please forgive my ignorance. But in defence of me and all the other ignorant buyers, when a device is sold with the argument that it is a fully functional Android device, one might suspect that you'd be able to run some apps on it without too many problems.
This is from the Boox site itself:
> The book is based on the Android 10.0 operating system, which allows third-party applications to be installed on the device and significantly expands the scope of its application
Marketing texts happen to be misleading more often than not. But this exact excerpt you cited looks innocent to me. "Significantly" is subjective, of course, but other than that it's correct.
