The Samsung Continuum will feature a secondary screen, also Super AMOLED, that will act like a news ticker. You can swipe it back and forth review different updates, including SMS, Twitter, Facebook, Weather, etc.
The device will have the same specs as the Samsung Fascinate, also on Verizon (i.e. 1 GHz Hummingbird processor, 336 MB of RAM).
This seems like a pretty quick update on the Fascinate, released at the beginning of September.
