- Screen must be backlit. E-ink screens look great in perfect sunlight and fluorescent lights , but if you're used to a phone/tablet, you'd be surprised how dim e-ink can look just sitting on a couch in the evening, with a lamp a few meters away. Backlighting fixes that.

- Web browsing on e-ink is not bad at all if you stick to text-heavy stuff. The low refresh rate actually discourages "endless scroll" behaviour. Get a browser like Kiwi that allows you to set the Vol. keys as PgUp/PgDn. That makes the lag a lot less perceptible.
