One of the features I'm most excited about in Ice Cream Sandwich is the camera. The new camera app really raises the bar, bringing a heap of improvements, as well as plenty of features we haven't seen before.
Perhaps the most impressive aspect of ICS' camera is that it has zero shutter lag. That's right - zero. Photos are taken as soon as you hit the shutter button. In last night's demo we got a glimpse of how powerful this is, as the presenter snapped off several images back to back with no wait time in between.
