I got one yesterday, and am having WAYY too much fun asking Siri random things me: What is the meaning of life? Siri: All evidence to date suggests it's chocolate.
I am wanting to get one...I've had a Blackberry for years, and now that Verizon carries the iphone I want to make the switch. But I KNOW the moment I get it they will announce the release of this mysterious, fabled iphone 5 that I keep hearing about.
Rumor I've heard is that the iphone 5 is coming out "summer 2012". That should be an interesting product as well because it is also the last iphone device that Steve Jobs was intimately involved with development of, apparently right up until a few days before his death. I've been using an ancient Palm device for about 4 years so I went ahead and got a 4s. It arrived Friday, while I was in Toronto. I haven't activated it yet but probably will within the next day or two I'm told that Siri is equipped with a ton of responses to all sorts of interesting questions. Several people have started blog entries on their explorations.
Summer 2012 would be about right. Apple averages 10-12 months for each iPhone update. Mac Buyer's Guide: Know When to Buy Your Mac, iPod or iPhone
For anyone that doesn't have an iPhone who wants to try out the Siri responses, Wolfram Alpha is what it uses to answer questions.
Not me, but I know some people with it already. I don't know why they got when I am expecting the next in several months.
