You put whatever apps you want on the Nxtpaper 14.
I have Pocketbook to read epubs & PDFs. Works WiFi with Calibre content server.
Nebo is far better than the cut down crippled version on the Kobo and better than Scribe for PDFs. Realtime conversion on Notepads. Import / export of PDFs and handwriting conversion to text on them. No need to send to someone's server.

I've very pleased with the Nxtpaper 14 for PDFs and Magasines. The 3:2 aspect and 14.25" is much better for than the Nxtpaper 11 for PDFs and Magasines, though just for notes alone the Nxtpaper 11 is nice. It's 10.9" and nearly 16:10 aspect.
