I remember it was kind of a quizzical but pleasant surprise... I had a Treo because I wanted the "do-it-all" device ("smartphone" was not a household word at the time) and the Treo seemed to have it all; in fact I figured it would be a waste of my time to stray but I also figured "why not" after the iPhone had been out a few months. So, in December 2007 I went to the good old local AT&T store and held it. And played with it. And I knew. It didn't have anywhere near the capacity or the features that it has now, but it blew the Treo away like an atom bomb; I might as well have never purchased the Treo--the iPhone killed it, incinerated it and left only a tiny trace of it in my mind. Since then I've been hooked on the iPhone, upgrading like clockwork every two years to get all the new features, but porting everything from my old phone to my new one every time. I did purchase a Mac Mini, but that functions only to do what the iPhone can't do well or yet, and as storage for my files and backups. I also purchased an iPad 2, which I enjoyed, but I traded that in when the iPhone 5S came out because even though it didn't double the storage capacity it does have the speed, lightness and ID sensor which was enough for me to make the jump from the 4S. I haven't been quizzically surprised like that first time, but I have been continually amazed and don't think I'll be switching to another manufacturer unless someone other than Apple designs a device that both fills my needs and blows everything else away.
