They have a function for it. From TFA: "Capture detail in every meeting with audio recording and notes. Make a mark on your recording while taking notes, then tap on the mark to play the exact audio clip. Review your content more clearly and efficiently."
This is pretty clever. If I recall, the LiveScribe Smart Pen had/has this feature. You just draw some symbol and tap it, and it inserts a voice recording at that spot. Surprised this isn't standard on these products now.
I have a hisense eink pocket reader(5.84") and it has an eink refresh button. It's hisense's degoogled android(only support chinese and english and some menus have weird grammar).
But what's interesting is that if you hold the extra button it launches into a notes app which has dictation and unlike googles own dictation it does a pretty good job at capturing both chinese and english without needing to switch.
I didn't try it for longer than a couple of sentences, but in general it's an interesting idea. It does have a lot of very nice eink optimizations that other devices don't have.
Contrary to huawei however this device has a snapdragon and allows unlocking the bootloader. There is however no dev community around this device and I don't feel like fixing the headphone amp.
There's a few more obscure Chinese options. Xiaomi has the 5.2" Inkpalm 5 mini. Runs Android but you need to convert it to English yourself. Aliexpress also has random 4.3" eInk devices.
