Clearly not for everyone, as it sports no high-end specs. But we have known that for over a year now, as it was first expected to launch in Summer 2013 and the basic specs didn't change too much.
For all those who can't live without a camera and entertainment (video and games) in a phone but want to try eInk on a phone and don't mind buying russian:
Yotaphone is selling the first generation of their double-display-phone since last year already and say they will start sale of the second generation device before christmas. At a price.
I gave up on the idea of a device that can care for all needs long ago (when Palm was still in business) and will have a look at the E43 for sure.
