Beta 1 lasted on my phone for 2 hours, beta 2 for 15 minutes and I've been using Beta 3 for 3 days now. so now that I am using it as the daily driver I'm noticing stuff. So, I don't know if it's only me but I find iOS 7 Siri to be so good. It's way more accurate in understating what you say, feels way smarter, it's responsive and blazingly fast. Especially the addition of Wikipedia is sweet as well. However the weird thing is I thought Siri was supposed to be a server based thing. A server that receives your voice recorded and decodes it, on the cloud, sends the reply for Siri to basically read/show it on your screen. If that's the case, how is it so much more different than iOS 6 Siri? Difference between iOS 6 Siri vs iOS 7 Siri is like day and night. They are so drastically different that it feels like they're two separate services. Even though I don't use Siri that often I'm anxious to see future developments on it. It certainly is going the right way compared to it's initial day-view 1.5 years ago. Imagine 10 years from now if Apple keeps at it... p.s. And I got the feeling they will keep on going with it. Future of tech seems to be wearable computers and Siri would make wonders with wearable tech. Imagine Siri and all it's capabilities at a possible Apple glass or even iWatch with bluetooth headsets, or many many stuff we can't imagine yet.
