Amazing. Thank you. I tried it with my current "keyboard" Kindle and it works. What a surprise - I tried it with my old KDX and it wouldn't work, and I never tried it again.
Feeling stupid right now
HOWEVER, now the screen feels so tiny (a feeling I don't have with regular Kindle books).
Waiting for the end of the year. I so hope they'll offer a larger screen kindle - a "paperwhite DX".
Thanks!
