I was blown away by the keynote speech of Apple CEO Steve Jobs at this year's MacWorld.
See the speech at

For an overview of the phone that could be to cell phones what the iPod is to personal digital music players, see
http://www.apple.com/iphone/, though the keynote video at the top link above is much better (though long at about an hour and forty minutes.
In any case, the amazing things are the User Interfaces that Apple is introducing. These are the people who brought us the mouse, and the scroll wheel. With the phone they're introducing, you can resize pictures with a "pinch" motion of your fingertips!
Cool stuff, and a neat glimpse into the future.
