While the launcher changed quite a between the initial SDK release when that video was taken and what shipped on the G1, the version of Android shown did support a drag-scroll gesture for scrolling through the dock and app drawer. It did not support kinetic scrolling at the time though. You can still download the version of the SDK that was released back in November 2007 (when the video in question was released) and play with that early version in the emulator. The G1 has never supported pinch-to-zoom or multi-touch in general except for in 3rd party ROMs and at least as of Gingerbread menus are still quite prevalent in Android (though D-pads and trackballs have fallen out of favor). The G1 also lacked an on-screen keyboard at its initial release (though this was added in an official update, Android 1.5 IIRC). I don't think anyone would argue that Android hasn't been influenced by iOS, but it doesn't seem clear that they were solely focused on a non-touchscreen Blackberry clone and then did a complete 180 upon the release of the iPhone. It's certainly possible that they did so before they publicly announced Android, but we don't have any direct evidence of that.
