I have been hearing noise lately about actual physical feedback coming from touchscreens by way of some sort of electrostatic sorcery, opening up the possibility of touchscreens with programmable tactile buttons. I've been taking a look around, and there seems to be a lot of contempt for mobile device control due to the lack of physical buttons (the multipurpose aspect of mobile devices aside). My big questions are: is this a game changer, or a gimmick? Is there anyone out there excited to see this technology applied to proprietary touch screens?
