And the iPad is a distraction device, one would need to disable everything in parental controls to get a comparable experience :)
I read a ton of pdfs on my iPad and am quite happy with the experience. Yes, epaper would be nice, but I don’t think there’s a good solution yet.
Distracted? Try the pomodoro technique.
Highlighting works great as it detects lines of text and can select even over multiple lines (the Remarkable doesn't do that). Writing quick annotations/notes with the pen works fine, but it's not pressure sensitive and the writing looks quite bad compared to real paper.
Long PDFs or books are hit and miss: There is no table of contents view and no support for anything besides PDFs. So you can't put e-books on it without converting to PDF first, and if you need to jump around in a (technical) book the lack of a table of contents or overview is very inconvenient. If you read through from A-Z then it's ok.
All in all it works great in replacing printer paper, but not so much in replacing your paper notepad.
There's no actual official announcement, but the lack of table of contents and a few small other things will probably be fixed by the upcoming firmware update, once it's actually released.
The DPT-RP1 really shines as a paper/article-reading and annotating device, but I wouldn't recommend it outside of that use case.
