Laws: Too Fast For Technology!!

Is texting while driving considered so urgent and dangerous that we must pass an oridiance without explicitly specifying in the conditions what electronic devices are included? We are setting ourselves up for too broad of a law in the midst of a "handheld" revolution. The technology is ever so changing these days and we must be more specific as to exlcude some electronic devices specifically or specify exactly which devices we are talking about. After all, the automobile is utilizing more electronic devices than ever with safety in particular as a concern such as gps, voice activation, built in cells phones, and automatic sensors. I'm not Nostradamous, but I see more time and money being wasted on an amendment in the very near future. http://www.austinchronicle.com/gyrobase/Issue/story?oid=oid%3A901848
