You need to stop thinking in terms of what YOU or a teenager would use it for.
Classrooms, board rooms, Webinars/seminars, digital signage (ever been to one of the new Marriott hotels?). The hospitality industry could be a prime user - TV, email, room service, movies, etc.. Watch your subscription Netflix on the hotel VioShpere in your room. Yes I guess you can also play games. I am sure I have left out dozens of other uses. Watch the today show. That big touch screen that the weather person uses is less than 1/2 of the Viosphere functionality. Are you really "a pro"?
