Not sure about the NeoReader, but remember that's it's an Android device so you can install other reading apps on it without any issues.
Personally I use KoReader (because I used to use Kobos/it's awesome) and it comes with export options - and options for literally everything else you could want. I also love how I can set a corner hold to bring up the book cover and the Poke 2's invisible screensaver option to get the cover displayed when I put it to sleep.
