Spent the entire day working with Copilot Cowork on some seriously complex tasks - not just simple document creation, but heavy-duty information organization, stakeholder coordination, and multi-layered logistics management.

The context retention is absolutely insane. It's handling multi-step workflows with dependencies across different workstreams without losing track of what's happening. This isn't your typical chatbot that forgets what you said three prompts ago - it's maintaining state across an entire day's worth of interconnected tasks.

For anyone doing project management or coordination work that involves juggling multiple moving parts, this thing is genuinely crushing it. The ability to keep all those threads organized and accessible throughout a full work session is a game changer for complex operational work.
