There are several other promised yet never materialized features as well. I check the forum daily for announcements looking for:
The ability to input text in eink with the keyboard - advertised as a feature in the beginning and removed.
The ability to use voice search and voice input. Speech recognition was a feature supposedly to be added in quarter 4.
Camera integration with apps like Evernote, NoteEverything etc.
Even the promised screen protectors have never materialized.
I am becoming impatient and hoping I did not invest my cash in a novelty. I will hesitate before buying a new model if none of the features ever come about.
