Obviously, we're still at very early stages with this tech. It's silly to compare it with smartphones and PCs, since it's a very different class of product. There are some barriers for entry but, as I said they will eventually get ironed out. The price of a full set with a fidelity grade matching the current high end sets shouldn't exceed the price of a games console in a few years.
There has definitely been a huge increase in interest with titles like Boneworks and the upcoming HL Alyx. The Valve index has been sold out almost instantly and there's reportedly a huge backlog of pre-orders for it.
