A couple of things to throw in based on the comments:
-The Gear VR is a neat experience - especially for simple tasks like playback of movies. But it in no way captures the same experience due to the lack of good positional tracking (you can lean over and look at an object like you can with the Oculus, and it does not have the GPU power to drive the same resolution and detailed experience) - think SD vs HD and then some.
-The Kinect is a bad example of comparison. There was no real “Wow” to the Kinect experience. It had shitty games, shitty “hold your arm up in the air until it hurts and wave to replicate the functionality of a controller”. It was simply trying to replace controller experience with motion experiences, and it never did a good job at that - at the end of the day the experience of what you were playing was generally the same.
-The early hardware also isn’t good for comparison, especially the DK1 which was super low resolution, had very early SDK’s without the same level of development that they currently have, and improper IPD (inter-pupillary distance) adjustment which would make you very sick very easily if it was not correctly calibrated. The current devices uses to adjustable displays to properly correct for that (Even the DK2 had this problem).
And regarding killer apps - that’s absolutely true - no one made a “killer” app for the Kinect. But Minecraft is coming to VR and that alone will sell millions of copies. Say goodbye to your children.
VR is an amazing experience for racing games, flight simulators, space flight, let alone the immersive nature of 3D movies. Until you’ve been literally transported to the middle of a forest you can’t realize how impactful that truly is. This will be a new medium for creating art and immersive experiences that to date, only folks like Disney have tried to crack, and now it will happen in your living room instead of a theme park.
More exciting, is this is just Generation 0. The future will improve a large number of the other issues like full body tracking, full body scanning, motion and gesture control, and most importantly, eventually cutting the cord that ties you to a box.
And yes, watching whatever you want on an airplane simulating a 100’ screen will be way better than trying to watch a movie on a 4" blurry SD headrest.
