Oh you are right. Intel made the hardware. Microsoft should be more buddy-buddy to them. And integrate features from them. I mean, at first, MS did make the surface for graphic artist. And Realsense 3D would've really helped with the 3D Printing. Heck, for the longest time, the MS store in Hawaii had a 3D Printer connected to a Surface to print things.
AFAIK Realsense 3D is an Intel thing and requires Realsense 3D (back) cameras which are different than the Hello technology (front) cameras. I whish they would include this but I suspect it may not work as well in the real world as the Intel marketing glossy might imply. So, yeah they developed some cameras and demo software in the lab... but if this was the killer app it sounds like, vendors would be allover it like stink on a skunk.
