Looks very easy to use in real life. But I’m curious how it will work with non-scripted use cases, such as: “remind me to get AA batteries next time I’m at Walmart.” I guess if Siri can learn where Walmart is (the same way it can learn who your spouse is) then my use case would work just fine.
Also, here’s the clip of Scott Forstall demoing Siri at the Apple event today.
