This is why I ultimately decided to go for a Boox Note Air 3 (sad they discontinued the B&W line). Apart from the lack of support for Boox firmware version 4, all the upsides apply without any of the downsides.
* I can comfortably read any PDF; I don't think the font is too tiny. This is the main reason I bought it for.
* Android means great data support, I can open any format and I can even install the kindle app and read the books I purchased there.
* Using the pen seems nice enough, I started doing some annotations although I didn't buy this device for that.
* Nice way to sort of "airdrop" files from devices on the same network
The bad:
* I am a bit unhappy with the battery life; I hope I will tune it at some point.
* the screen is a little dark, so the "frontlight" needs to be on more often than a black and white e-ink device
The weird:
* the built-in AI assistant is trained in the PRC and has quite interesting opinions on current events and recent history.
