Brainstorm

I have a Cannon steady shot, which has a motion sensor that rotates the picture between portrait and landscape on the built in LCD depending on how I hold it. Very nice for looking at any pics that I have taken in portrait mode (tall buildings, captures of business cards, and documentation, and oh yes portraits :-) ). Looking at these on a widescren LCD with black bars is NAFF, and cropping and rotating the picture will just bugger up the framing when looking at the same pic on other devices. I dont know if the n900 does this, but it would be a nice feature.
