I'm excited. The HoloLens seems like the perfect tool for augmented reality. Can you imagine paintballing with it? (I'm sure the military is watching closely.)
But that price... now that's beyond the reach of most regular folks. And I wouldn't want this to be a tool for only the rich. It would be great if Microsoft open sourced the hardware and the software so other companies can make HoloLens-compatible hardware and software that's maybe 80% of the functionality for 20% of the price.
I'll be watching HoloLens closely because it seems we are entering an AR and VR world.
