I’d actually like to see a lot more devices like this, and find the reMarkable particularly interesting. The main negative imho behind the cost compared to more general purpose devices.
Which is to say for most folks, you may as well buy an Apple Pencil and the cheapest iPad that’ll work with it. It won’t be the same thing but it would be more value to the average user.
E-Ink and styli are both tech I’d rather like to see more commonly used, so my bias is fairly obvious 😜
