tie touchscreen keyboard to knock/vibe control for feedback(pat pending)

not sure if the current 'vibe' control is fine tuned enough for just a single knock but a good first step would be as short a buzz as possible on key presses. Then, get FIC to mod the vibe control for a knock pulse before the consumer release and they'll probably win over some customers and maybe the press with a touchscreen keyboard with feedback.

In the meantime, someone who's got one of these should implement it before Microsoft patents it.
