I am getting tempted, no small part of the temptation is the fact that its software stack seems entirely open source, based on Linux and the source code is on Github. That seems just perfect. The only thing that bothers me is that it is somewhat pricey $300+ and am not too sure about its performance.
I lug around quite a big pile of technical pdfs. If something can reduce that weight I am up for it. So the decision for me is whether to go for a tablet or a e-reader like onyx boox, it seems to be a "few of a kind" if not one of a kind.
EDIT: Thanks, whoever upvoted this back up from grey, it seems to have annoyed someone.
