When I first got my 4S I just played with Siri for the first week. It was nice but the load times were too slow and it would only understand me 70% of the time. And then the other night I felt like using Siri to set and alarm and I was surprised how good Siri was. Siri instant gave a response (only 3 bars), and then I tried a few other things and Siri understood me every single time. I think I'm going to have to start using Siri more. Setting a clock with Siri is much easier, and "note this" or "remind me this" is cool too. Have you guys noticed an improvement in Siri? Or is it just me? Is Apple using our voices to improve Siri?
