Sounds weird. I doubt that these rumors have any truth in them.
Sounds especially like work Apple don't have to do. Apple have invested so much in having top notch accuracy in their touch panels and then based the entire iOS around that, just to go "OK, let's ignore all that" and add complexity, cost, and factors that can break, to their devices? Their customers are even telling them that they want keyboard-free devices via their sales figures. Going keyboard free was one of the distinguishing features for the iPhone.
Not as long as Steve Jobs is CEO, I think... This would be a 180° turn for everything they've worked towards in their designs. And I seriously doubt many other top people at Apple would like this either.
