I hope that this isn't the real iPad 5 design. The mini is fine with a small bezel because it is small and light, but you need some space to hold onto the big iPad. I foresee much more inadvertent pinch-zooming with this design.
The ipad mini allows normal functionality while resting ones thumb on the screen. It can distinguish a resting thumb from a pointing finger.
Give it a try. However it only works with the mini at the moment, but I suspect Apple will add this hidden gem to the new thinner bezelled ipad 5
