"In March 2006, a Delaware federal court judge threw out the patent
      infringement suit, deciding that not only did the PowerTouch not infringe   on LeapFrog’s patent, the patent was obvious and therefore not valid."

The under pinning firmware set connected to the interface is indifferent.

It was the right decision

Thought on interface....What underpinnings will they utilize for their interface?
