More about dual screen devices

At a closed IFA meeting, a working prototype of a dual-screen device, LCD and eInk, was shown. The creators are still negotiating with major vendors, plus it became known that one of the popular mobile phone manufacturers also began work on similar devices.

Amazon did not have time to get a patent , as someone has already made a ready-made working prototype.

I do not know about you, but in my opinion, in this eink form factor, this is unnecessary. If you can still read books normally on a two-sided Kindle, then on such a small screen it is no longer so convenient.

Although, I also read a bunch of books from the screen of an old Siemens on the way.
