Well let's all just be happy it's not fucking Apple for fucks sake.
It was a joke that I didn't make properly, apologies for the confusion.
I'm glad it's not Apple or Google bringing this to market.
I love that it's Microsoft (check my sig)

Also, that microsoft holo doesn't impress. The uses for it are pedestrian. Holographic tech could be used for so many other awesome things like projecting heart rate, outlines and vital signs during operations, projecting a design for a skyscraper, live stats over each players head during live sport, getting a name real time for a tropical fish while you're diving etc.
Microsoft already talked about using it for everything you mentioned in their video (the long one).
