Boox e-ink tabs do the same thing, but they're Android underneath so it's not locked down to Amazon and dependent on partnerships with Microsoft to add an export button.
Amazon could score an easy win and force a lot of Boox owners into their direction by getting an import ban on Onyx devices.
The O’Reilly learning app works great, too.
Drawing functionality is as good as the current state of eink screens.
Pretty sure I wouldn’t want to lock myself into the Amazon content ecosystem ever again.
There’s a new version which uses a color eink screen. I’m speaking of the greyscale one.
I'm starting to notice the battery on my Boox doesn't last as long as it used to, so I'll probably replace it with a Kindle.
I got the Ratta Heart of Metal Pen to use with my boox, and it's a really nice writing experience, and I don't have to replace tips (I found the boox tip didn't last very long). Just added a screen protector and it's been great. https://supernote.com/products/heart-of-metal-pen
