You know, that idea has some merit in an offbeat way, although there is potential for it backfiring ("heard of vaporware? looks like the N900 is paperware").

What about this: early on in a video people hand off large pictures of an N900-- only the pictures are animated by annotations describing functionality. Finally someone discards the print, and a character played by a person with an actual N900 picks it up-- and it becomes a real N900.
