This afternoon during Apple's financial Q1 2016 earnings call, Tim Cook was asked one question about VR. When asked about whether or not virtual reality devices in 2016 were a niche product, Tim Cook had the following to say: "I don't think [VR] is a niche, it's really cool and has some interesting applications." That's it. Does this mean Apple is investing in virtual reality hardware and applications? Not necessarily, but it certainly doesn't discount that idea.
