i think ms is smart to invest in the halolens technology. that shame would be cool if it actually worked as advertised. but yeah,.. it has to work first. in a few years time they can probably fix the FoV problem cheaply enough and get better tracking technology for walls and stuff. actually it is the input that i'm most worried about because voice control just isn't 100% enough especially in non-english and the wagging the finger control looks terrible.It will be great for a lot of things. Gaming really isn't one of them. AR is too limited in the experiences it can give you. The technology is definitely something I see becoming huge for home repair and improvement, construction work, education, etc.
still. if/when it works it will be a big hit i think.
