Well, if you use the Nikon playback with that sort of discretion, then it does not need to be in top position next to the LCD screen. Sony determined its priority correctly and put it in the appropriate location.

The Sony automatic playback is not annoying since if you are not looking at the LCD screen you would miss it. It stays on for less time than the push button approach and therefore does not cause a battery drain, and of course it CAN be turned OFF in the preferences.
