For an example of the phone Amazon should have built, check out the Yotaphone 2: https://yotaphone.com/gb-en/ Wonder if Amazon could buy them?
Wow, did not know about that! What a shame that Amazon didn't go with the dual e-ink/LCD idea, given that they're practically singlehandedly responsible for e-ink going mainstream. Throw in free-with-Prime, Android, and a few carrier discounts (e.g. free data for a year) and I'd happily dump my iPhone in a heartbeat.
Huh? The Yotaphone already runs Android, and not an Amazon-crippled version at that. :)
