I would say I am platform agnostic. As I said before, I have had every platform since Dreamcast and have felt different companies ahead of the pack at different times. To me Microsoft is pretty far behind this generation. The biggest piece of evidence that dooms them in my eyes is that the two games vying for GOTY are not available on Xbox. In fact, Xbox has nothing that even approaches GOTY (for the current year) status at this point. I understand that not everyone is into the exclusives on other platforms, and in that case, the Xbox can make a fine choice. However, when you are not even in the discussion for GOTY, it makes it tough to make a lot of headway, especially when all of your games are available on PC which is even more powerful than the most powerful console ever.
From my view, the Xbox has the superior controller, better online experience, more powerful when the X arrives (though I don’t think as much more as MS wants you to believe), and Ultra HD Blu-ray. Even with all those adavantages they are getting crushed in sales. The reason is game library. Sony simply has a far superior library of games and has focused on games from the beginning of this generation. If Microsoft could match them in games, the Xbox would kill. But MS is more interested in trying to make the Xbox something people don’t want. First it was a media PC and now it’s a Windows 10 box on your TV. They need to get some games.
You keep mentioning game library, and I think you are way off on that. The gaming library is huge on the Xbox, specially with the backwards compatibility to the 360, and they are exapnding that to go back to the original xbox.
