I find it useful, so here are some concrete examples from last few days.

As a baseline which many skeptics will have a hard time accepting for their own usage - I think there is a correlation between utility and trust (even which is not truly earned). If you don't let it capture memories and learn about you, and you don't connect it to external tools like email, it's less useful. But I think of it usually like a ChatGPT w/ extra tools and knowledge.

I just moved, and last night I asked my agent how to test how safe the soil in my (urban) garden was, and it found some warnings from my city government, and suggested a particular test service that is available in my area. Since it knows exactly where I live, it was able to find recent warnings of contamination in my neighborhood, and suggest specific chemicals to test for.

Additionally, I give it (read only) access to my email, and it'll ~2x a day notify me of some important email. I'm working with a contractor, and getting emails from them bumped, or getting emails about AWS usage alerts pulled out of inbox and notify me directly is super helpful for filtering the noise of my crazy email volume of 99% spam.

Also, as others have said, it's easy to take a picture of a flier, and say "add to my calendar".
