Jukka just posted "No such thing as silver N950 except for Transformers 3 ;)", which reminded me of the movie appearances of the Nokia 770. But first to the silver N950 appearance which I somehow missed: A quick TMO "site:"-search reveals the obligatory thread for the N950-in-Transformers 3 appearance with a frame grab by ro25anav:
As for the 770, it starred in a Harold and Kumar movie, in a Fantastic Four movie and in a Die Hard movie, but you probably already knew that. The 770 appearances are well documented (with screencaps) over at starringthecomputer.com if you don't have the time to watch all three movies. Any other movies in which Maemo devices appear? What about the N800, N810 and N900? Googling doesn't really yield any useful results, with most hits being about "watching movies on device so and so".
