Microsoft introduces the Surface Hub, a wall-based display made for businesses - not consumers. If the price didn't do you in, the functionality certainly will. While using such a massive piece of equipment is certainly an interesting possibility for the average consumer, this 4K 84-inch display will facilitate meetings at your business. That's what it's made for. Not playing Angry Birds. Not acting as an 84-inch touch arcade... though using one as a pinball machine or a digital air hockey arena WOULD be neat.
