It depends on the price they label on the Hololens. The concept itself is pretty good, but people wouldn't pay too much for it. As the Hololens has Windows 10 as its Operating System, people have to keep in mind that they have to rely on the Windows apps( built-in or third party apps ) only. Therefore other Operating System users might not want to buy the Hololens if its really expensive.
It has a good concept, but I think it will flop like Google glass. Mostly because our society is focused on appearance. And who wants to look like they just got of the star ship enterprise. So maybe a product people use ate home, but not in public.
Looking at the concept of the hololens, it looks like you're literally wearing the star ship enterprise on your face, but you're smiling because you're rich af and everyones jealous
