I've not got a HoloLens. Or an Occulus Rift. Yet. But I've had a go with both of them and they are really, really interesting. The way I see it, there are two game changers coming round the corner as far as computers are concerned. One is the Internet of Things, the other is virtual/augmented reality. You need to know about both of them.
You can get to play with the new versions of reality at a c4di event on Thursday morning this week, which is open to all. Sign up here. It's free. I'm going.
