Amazing. Steve Jobs does it again when he announced the Apple iPhone at Macworld 2007 just two hours ago. Engadget has a great recap: http://www.engadget.com/2007/01/09/the-apple-iphone/

The best feature, to me, is the multi-touch interface. It's a very intuitive way of interacting with the device. I believe it is the same technology that was shown about a year ago by a researcher called Jefferson Han called "Multi-touch Sensing through Frustrated Total Internal Reflection". Here's the URL to his research page: http://www.cs.nyu.edu/~jhan/ftirsense/index.html
