Next time I need to change cubes with chinese characters from clear to red or rearrange alphabet letters with a friend, this will be a viable option. I always find it unsettling when I see demos of "new user interface technology" that involves people performing tasks that seem primarily designed to look visually impressive and only secondarily (if at all) are related to a task someone would actually want to accomplish. Show me how this can help me work faster. I'm currently unconvinced that this system is superior to a mouse + keyboard. I'm not even convinced that the demo tasks couldn't have been completed just as easily using keyboard shortcuts and a mouse.
