I like that Nokia has laid out visually the physical 3d objects that model the interface behavior. iPhone applications frequently seem to ignore this very basic idea. The level of realism even gets down to specifying a common light source which all icons and 3d elements should reflect.
I also like/am curious about the color guidelines, namely that each application should "own" a single highlight color, which then gets used consistently in its headers, labels, and form controls. The applications demoed in the docs have a much more consistent and less kitschy look than many brightly-colored, inconsistent iPhone apps.
