Try looking over the Engadget review of the Nook Color sometime, and definitely watch the video. While I never can figure out how Josh Topolsky got that job (he's truly a techno weenie and clueless at the same time, weird), he does a somewhat half-decent job of showing off most of the features in a quarter-decent way.
