Galaxy s4 will have tilt scroll function among other things. Why didn't apple think of that first? I have been writing to apple to come up with some sort of auto scroll and Samsung did it first. Can you imagine how convenient it would be to be able to scroll vertically or horizontally with a just a flick tilt of the phone? Make it so that I can 'Flick(tilt) and the screen will scroll 90% vertically or in google image search situation 100% horizontally. And a gradual tilt will slowly scroll the screen according to the degree of change. And flick in the opposite direction while autos scrolling will stop scrolling.
