[whopper]

they are ok devices, not great.

the software is mediocre, I don't use what they offer but third party ones like librera. You cannot expect the support of a first class brand, but they are doing it better now than in the past. The good thing is that is android, so, until certain point you can choose how to use the device through apps instead of being locked into a proprietary software

the cover can be used as a stand, similar to surface or ipad

onyx is a chinese company.

As a device to browse sites or use like a monitor, it is a 2/10 compared to tablets.
As a device to read books or pdf's full page or 2 pages per screen, it's the best one available with eink.

it is a niche product with a high price, whatever the value you get from it is personal For me it was worth it.
