Pheh, they forgot the best application ever: iPhone-controlled vibrator: http://www.ohmibod.com/bodyheat/ http://www.ohmibod.com/bodyheat/ I was at a presentation by the app's creator, apparently the hardware was already available through some company, so you could theoretically do it with any device that outputs to a headphone jack. The iPhone's touch interface simply provided a ... unique and apparently (don't ask me!) expressive method of control.
