I have a techie commercial in mind. User A with crap-phone is struggling in his day job, user B (the OP) comes in and does what he wrote in the first post to the utter amazement of the other guy. User A looks at him and User B says "It's Maemo". Cue Nokia logo and fade to black. (So basically everytime the N900 does something amazing you just explain with the "It's Maemo" line).
