The Scribe is neat, but it's too small (same goes for the Remarkable devices).
It wish it was A4/Letter size to read PDFs at full size. There are a few devices like that out there (I've heard the Fujitsu Quaderno is nice), but none of them can be used with books purchased at Amazon.
And yes, I know about Calibre and the DeDRM tools. They don't work on KFX files and the workarounds degrade the book (you lose typography improvements that are only in KFX).
I'm also disappointed by the Oasis being discontinued. I wanted to trade mine in for a USB-C version.
