Ok, daveb started with the visuals, so here are some actually taken from personal experience:
Father and daughter sitting outside on a starry night. Father points to the sky at a bright point of light, and then he holds up his N900 and he shows her a picture of the tiny planet Earth beside the huge curve of Jupiter...
qole, thats almost an app idea.
it could just be used for AR to hold up the device to where you are looking and have it annotate the star names in the centre of the view.
fix it onto the side of a telescope and display detailed info on the focused area.

The Nokia N900...Nokia's premier phone, and revolutionary device--is it a computer or phone or is it something Nokia can't quite come out and say when it's gonna be released...

I'm on it! I have done some work to put a fingerfriendly UI to Stellarium, but at least in scratchbox it is painfully slow, so I'm waiting for my N900 before i put more work in that..
