I thought the same thing. There is real innovation in tablet computing available through this avenue. The current haptic feedback that some devices offer is really inadequate. To give you actual controls that you can feel would be a leap forward. Also, if you think about the way Apple typically does these things, it would be a huge advantage if they got there first. Apple has a tendency to buy years worth of production from a given vendor, if they could tie up access to this technology for a year or two while production ramps to accomodate demand, they could gain a huge lead (well, larger than they already have).
