+1 for Raindrop, that app is amazing, I keep watching for a self-hosted version/alternative that is as good and they are getting closer. The killer feature for me is being able to highlight stuff and then when you visit the site again you see what you have highlighted (in addition to saving them elsewhere). I also pay for premium because it’s great, I don’t use a ton of the pro features either.
I just wanted to add this video to your comment because e-ink is so cool and this guy has a bunch of macro shots of the displays that are awesome and you can see the particles in the screen changing colors.
