I'd rather just focus on the 10% that is the detailed content, versus 90% hype, but to each their own. I don't need to be told for 3 hours that every minor feature is an Earth-shattering event.
Honestly this blog post is 90% gibberish. Skimming over it, I just see meaningless word salads like "navigat[ing] the current environment", "design[ing] a Surface for every person", and "stay[ing] connected to the people and content that matters".
