@Pomtroll, The demo video on the B&N website shows the dictionary being used.

@randyharris, The specs show support for ePub and PDF and four image types (gif, png, bmp, and jpg).

Just out of curiousity, do any of the earlier or current nooks have a landscape reading mode? I know the nookcolor does not. No landscape is not a deal killer in my opinion, but it would be nice to have.
