Update: Video after the break!
Update 2: Okay, we got some more info on that screen. The entire front of the phone is one huge four-inch screen, with the Android buttons more or less painted over the lower third -- the screen lights up underneath them in white to illuminate them. Samsung says it's just easier for marketing purposes to say it's two screens, but that they're selectively turning on the bottom portion of the display for the ticker. As far as battery life, it's a 1500mah battery that'll last about a day, we're told -- the lower screen turns on whenever a notification comes in, but since it's a smaller screen the battery life is on par with the Fascinate.
We also learned the "grip sensor" isn't really grip-based at all -- it's capacitive, so just lightly touching both sides of the phone lights up the ticker. It's pretty nice, although super easy to set it off by just holding the phone. Samsung says there will eventually be an API for third-party apps to use the ticker, but right now they're just focused on their core experiences. As for Bing, well, no one's saying why some Verizon phones get Binged out and some don't, but every indication is that Verizon calls those shots, not Samsung. We're also told that an Android 2.2 update will eventually arrive, but there's no timeline yet -- and there's a real chance this'll launch with 2.1 after 2.3 hits. Developing...
Update 3: Added a quick macro pic of the buttons after the break -- you can see how it's just one big screen. We also took some side-by-sides with a Captivate -- the Continuum is thicker and narrower. Samsung says the narrower size is designed to appeal to women, who generally have smaller hands. %Gallery-107011%
