There's one in every picture. Some fool who ruins your shot by closing their eyes just as you hit the shutter button. Well, Canon's looking to make that a thing of the past with their new Blink Shot technology, which won't let you take a picture if your subject's eyes are closed. I normally look half asleep in my photos, so this might be worth checking out, though I don't see it being anything more than a gimmicky feature for point and shoots. No word yet on when we'll see the feature in cameras.
