I left that out because VR also requires an expensive computer -- expensive at least compared to what most people have. Rift, for instance, requires not just a discrete GPU but a pretty serious one (GTX 970/1060 level), in a market where only about a third of PCs sold at retail in 2016 had a discrete GPU at all (see http://www.anandtech.com/show/10864/discrete-desktop-gpu-mar...).

So, if by "VR" you mean Vive/Rift-level VR, very few people will have a computer already lying around the house that can cut the mustard, even if they bought that computer relatively recently.
