Same here. I use Siri for everything that would be slower to do by hand, or my hands are busy.

"Wake me up in X minutes" "Call <person>" "Remind me to ... [in X hours, in the evening, when I get home]" "What's the weather like today", when I'm getting ready in the morning "What's on my agenda today?", while driving to work

I rarely use Siri to query for specific data, which seems to be the thing Google Now does well. Siri for me is just a way to operate the phone faster.
