Every innovation is valid, but it's not something that everyone needs to have. I particularly like to keep myself always up-to-date so I may possibly buy XBox S (but this is a totally personal preference).
I like being able to live all the advances. You know, be a part of the path.
I agree with @wiseagent! When it comes to the consumer, it's the principle of if they need the actual product. In my case, I would say no. First, I'm primarily a PC Gamer. Second, I have a perfectly working XBox one I'm very satisfied with. Because of that, I don't see myself upgrading anytime soon.
