More importantly...
When will they work on a mobile phone camera that will slap sense into the idiot user when they try to take video in portrait mode?
I hate it when people do that. Just one example:
A friend was showing off some holiday videos on his TV. The TV is of course wide-screen but the video is portrait, when asked why he chose to record in portrait when he intends to make a DVD for use on a wide-screen TV his reply was "Well, that's how my phone takes video".
Cue facepalm.
