What can I say, I'm a compulsive early adopter =P I also have an Apple Watch and a Myo armband, but haven't found a ton of compelling uses for them yet. I didn't want to miss out on the opportunity to develop for it early if I was wrong and I had the cash to buy it.

The difference from 15 years ago is that the hardware is actually here and practical. We have the tracking and displays and they are actually really good. It really creates presence, there is 0 comparison between Oculus/Vive and VR experiences of yesterday, such as the Aladdin ride in Downtown Disney. Hell, HTC is literally pivoting the entire company to the Vive. HTC/Valve + Facebook + Sony + Samsung is a ton of top-notch engineering effort being put into just the first generation of devices/software.

See my comment above, but basically I imagine it'll create new media/experiences rather than replace. I don't think "floating monitors in space" will ever be compelling (maybe in AR), and I don't think "movies" as we think of them now will be practical (though I do think there is room for a more "theatre-like" approach).
