When was the last time Microsoft had a unified vision that was focused on building an amazing line of products that integrated well with each other?

I can only think of short snippets in history where they moved in that direction for maybe a year or two & then went scatterbrain.

Microsoft has benefited from a monopoly in the enterprise and has never been forced to innovate from a product perspective. See Slack/Teams as a case study of how they have operated when even slightly pushed.

* Edit - .NET, C#, TypeScript teams are an exception to the above. Highly underrated. Amazing talent there. Not sure who all gets credit. Anders & Mads for sure though.
