Thanks, guys.

For X-ray, I figured that would be the case--it won't be a feature that I'll count against the Kobo then, since I expect most of my content will be side-loaded so I probably won't make much use of it on the Kindle anyway.

As for the dictionary--what makes it better on the Kindle? Could you download or select which English dictionary to use if you find the definitions are inadequate for a particular dictionary for either Kobo or Kindle? Does the Kobo have translation?

And for the bookmarked pages to quickly refer back to on the Kobo, that actually seems like a way better implementation than what the Kindle has (if it doesn't have this feature), since without this feature, it can only really jump between 2 pages quickly. It seems quite intuitive and easy-to-use--just bookmark all relevant pages and open the bookmarks in whatever ideal sequence and flip between them.

So far I'm really sold on the Kobo Aura One because of the KOReader which is apparently not available for the Oasis 2 (yet?) along with the bigger size.

It also seems like the KOReader devs are receptive to feedback and feature requests so maybe they can add in annotations for PDFs.

For the Aura One, what's exporting notes/annotations (if any), or data in general like? Could you export it via email? Even better--could I use rsync or syncthing to (automatically, if possible) sync between my PC and the Kobo? Of course I'd rather avoid wired transfer.

P.S. Only thing I'm slightly hestitant on is that the Aura One is nearly 2 years old and I'd hate to get one now only to find a successor will be available by the end of this year. Just from looking at the release dates of their devices, it kind of seems likely, but I haven't heard of any news. The Paperwhite 4 is still in the back of my mind because it will have the natural light feature and is for sure going to be the best bang-for-your-buck, but I'm pretty sure it will be too small for me. Not considering the Oasis 2 anymore.
