I think there's an actual keyboard on the other side of the e-ink screen. So It appears to have an lcd display, an e-ink display and a keyboard.

No the keyboard is a virtual keyboard using the e-ink display.

You can type, in the sense that what you type is appearing on the fast color screen not the e-ink, so you can go as fast as you want.

But it's probably terrible because there are no mechanical keys, just a flat touch screen displaying a virtual keyboard like an ipad.
