Will we soon be able to TOUCH a rough surface on an iPad?

Familiar with Senseg? Check it out: http://senseg.com/ It's a touch/feel sensitive screen that's supposed to show up in consumer products sometime in the future! You will be able to tell if you are touching a rough or a smooth surface, a ball or a cube etc. This would be SWEET!! I have no idea if this will happen or if it will happen - but I will be in the line at the Apple Store the day it does. Bring it on iPad + Senseg =)
