Yes, it is a huge problem. One funny way to look at the problem is that if you told someone twenty years ago that in the future there would be a TV set on every desk in every office, this person would not have believed you. Yet, the actual situation right now is much worse than that.
This is going to be a huge health problem ten years from now (it must be already the largest productivity killer in the workplace), and great solutions for this will be profitable some day.
