I would 100% like to try out every e-ink device out there, but price is definitely a factor.
They tell me the Daylight is blue light free, but isn't every e-ink without a backlight? I like how the Supernote is more tailored for handwriting, pen tip doesn't need replacing, and they let you change the battery.
I can see a deep-dive into the e-ink community online wisdom in my future.
