Anyhow, since if you have a 4S you're going to play with Siri, I've found that it's really quite useful even when not in a hands-free situation like driving. I've found it very useful for setting reminders faster than I would be able to manually, which I found quite surprising. I'm looking forward to finding more things like that in the future.
Remind me to... (like you said) Wake me up at/in... Call [name in my contacts] Call [place not in my contacts]. Siri looks up business for you. Note [something I want to make a note of]
