I am on record here, stating more than once, that the iPhone 4S would be the first model of iPhone I haven't owned. I quickly changed by mind when I tried Siri in the Apple store. In my opinion Siri is as big a leap forward as multi-touch was. I use Siri throughout the day, every day. It very tangibly makes my interaction with the iPhone easier.
I'm half way through, first book I have ever read on my iPad. I have followed Steve Jobs for more than 30 years yet most of the information in the book is completely new to me. I will miss Steve forever.
