Seriously, is this meant to sound affordable? $400 for an apparatus that only works for a handful of games, not including the price of the game and the price of the platform you already bought to play the game.
No, let's have a talk about why streaming and VR won't really break through: the barrier to entry is too high. For streaming you pretty much need not only fiber but also to live in a spot deemed worthy enough to have a data center close. Meanwhile VR is just superfluous luxury. I'm sure people who threw money at it can write essay upon essays about how great it is, but that doesn't really change that it's a luxury that's low on the list of many people's priorities.
You can't really compare it to other luxury items that went mainstream like say the iPhone, because when that came out it was a product that covered a demand not many people knew they had at the time, and developed their consumer base from there. And Android had an incredibly low barrier to entry at the time it launched with HTC devices. Meanwhile VR isn't something people need, most people are content with never getting it. In fact using it makes some people sick.
Companies can turn as many desired IPs as they want in to the next tech demo showcasing their technology they want to sell, but will it ever really break through until they lower the entrance fee?
