I looked over some of the amazon reviews, and they seem to be talking mostly about issues in older versions (2018) of the software, which I don't have direct experience with, but the software has gotten better, even in the time I've owned it (they just released version 2.x of the SW).
That being said, there is still room for improvement, particularly with reading (vs writing, which this device is very good at).
I mostly use it this to replace stacks of notebooks (my brain thinks better with pen and paper in hand, but with all the digital conveniences in hand. This device is the best that I've tried for writing (and I've tried many, including an ipad pro)
Cons: historically, the price. No blacklight. Clearly the device has been optimized for writing, not reading, although supposedly 3rd party ebook readers like Apollo are good (the device is not locked down and has a hacker community).
