My 8 year old son knows more about the Rift from watching his youtube buddies than I did. That's when I realized its gonna stick this time. He had a chance to use it at his summer camp and now he's saving his allowance so he can ask Santa for one and buy a Kinect to make VR experiences at home (Luckily his superhero dad is a PHP and C# programmer by day)
Little kids love even the simplest buggy broken demos. They go wild for it.
