Oh, I definitely think so. Another benefit, so far unspoken, is a healthier user base. Instead of sitting on our bottoms and shoving a mouse or joystick around, programmers, not just for games but also for office applications, could/should/might be urged to develop apps that needed the user to interface using the entire body, as Cruise was shown doing, so as to get some exercise back into our daily routine. Office workers who are on their feet leaping and twisting around would be in better shape and that would lower health care and insurance costs over the long haul.
Bill Gates has been wrong in the past, and so has Steve Jobs, but I think the man is dead right with this one.
Yeah, go ahead and laugh at the idea, but wait and see.
