Having said that, if you have some substantial argument to back (or challenge) this point, let's hear them.
I will offer a backing point: Microsoft technology rarely comes up on HN or Techcrunch. Not that it's being despised, it's more like hackers and entrepreneurs don't seem to care. Making a leap of faith we will conclude that those are the people who will shape the future, and conclusion of Microsoft's irrelevance is within reach.
