I wonder what they perceive as the target market, gaming? I can see industry uses and gaming, but if it's going to be mapping on my physical world, it has to be as subtle as eyeglasses. Someone needs to make eyeglasses that can do this and link to the computer in your pocket or on your wrist.
Microsoft, I believe, still believes in buying markets. Their constant crowing about how fast the Kinect sold, for example: Sure, throw millions of dollars at titles that require Kinect, you're going to drive rapid adoption. That doesn't mean people particularly like interacting with Kinect. Microsoft was also shoving tablet PCs down everyone's throats long before the iPad... and now, in an era of iPads, they're still trying to convince you that the iPad they're selling you is better than an iPad because it's also a tablet PC. The original Surface - their multi-touch table - was a classic solution-in-search-of-a-problem, as most VR doohickies tend to be.
This is a problem of energy density as much as anything. There just isn't room to fit all of the electronics (even if you offload the heavy processing) and enough battery to run them for ~6-8 hours in the form factor of traditional eyeglasses. Of course, both component size and battery energy density are getting better all the time, but not at a rate that will allow for the HoloLens product to be shrunk to that degree in less than 5-10 years. That said, I tend to agree that we need to hit that point before we see widespread adoption.Someone needs to make eyeglasses that can do this and link to the computer in your pocket or on your wrist.
