Craze performing glass surface on Samsung Galaxy S4

Comment on Smartphonebay.net:
The glass surface of Samsung Galaxy S4 is tough. However, the test seems not quite relevant to the damage caused to the glass surface everyday. They should also include a test in using the touch digitizer surface and tapping the surface 1000 times / minute at a single point to check whether the surface can resist scratch from everyday use or not. Wish they planned a more meaningful test next time.
