content: It isn't touch screen. It is customize display and also you can use your phone as a controller. If you update the firmware you could make your own commands. $90 is a lot but a regular plaque is ~$50 we have a large display 5.5 inch but also there will be a battery and mount. The mount will be screw or tape on for doors and for cubical walls there will be clips. For someone working in an office  $90 isn't a lot if it helps get your $1,000 or more raise :)
