With our P&S we do/used to do what you describe. We used to do it for the 1st photo of the day, but not purposely waste a frame (I can understand you doing that if the pics have some 'artistic' purpose). These days we tend to leave it on permanently as all the pics taken with the camera are family or holiday snaps and having the date on them doesn't bother us at all (they all end up as 6x4 prints in an album).
