I'm finally upgrading from my beloved iPhone 3GS to an iPhone 5, one of the things i'm very excited about is Siri but I wanted some honest opinions on how useful Siri actually is in a practical sense. Is it really useful for adding events/reminders or is it the case of most other voice recognition services and it rarely gets it right first try? Part of me really wants it to become a really useful feature that I use daily, but another part of me thinks it may just be a novelty that will get boring/tedious after the first few weeks? I'm really interested in using it in the car, I connect my phone via bluetooth to my car stereo for music streaming and phone calls. Has anyone ever tested using siri using a car bluetooth stereo, does it work using the cars mic used for calls etc, or will I still need to speak into the iPhone mic? Sorry if this has all been discussed to death before at the launch of the 4S, but searching Siri on here is information overload and I was hoping for some more current opinions a year later.
