Got my hands on a Hisense A9 e-ink phone from a liquidation site. SNAPPED IT UP for $89 shipped. Thing runs android, has google play, 6.1" e-ink display. Been my daily reader for 3 months now.
Battery lasts a week. Read in full sun no problem. No blue light killing my sleep.
Before this I was on a hacked PSP from 2008. Custom firmware, Bookr app. Fitted 4,000 books on a 32MB memory stick. Yes, 32 MEGAbytes. Mostly plaintext + heavy compression. Took 40 seconds to open a PDF. Still worked though.
What are you all using? E-ink phones? Old palmed devices? Some weirdo linux e-reader I haven't heard of?
Tracking price history on these Hisense units btw. Was $220 last year, now floating $90-140 depending on importer.
