I have been using this application called lifeblog on my n95-8gb which actually shows all the pictures/videos/sms etc in a timeline. The app is really nice and it is compatible with nokia photos which is the pc client.

Anyone knows if this will be available with the n900/maemo 5?

Thanks

nokia lifeblog was discontinued and not been on any device of the last 12 months and used to have a pc client of the same name where it synced absolutley everyuthing between the two.
EDIT: it got replaced by photos mobile client on newer devices and uses the PC nokia photos in a simlar way but some say its not as good i cant really comment how good it is though as i dont use it since it changed from lifeblog
