I went to MacWorld to check out the Apple iPhone. I think that it is even more impressive in person than I was expecting. Its smaller and much thinner than I imagined from looking at pictures, and watching the live on-stage demos made it clear just how much of a step forward in usability this is for a mobile device.
I took the picture above using my Treo650 of someone else taking a picture with a Treo650, so the size can easily be compared. I was embarrased to get the Treo out anywhere near the iPhone, it just felt wrong. The overall width and length of the device is similar, but the Treo is about twice as thick. I tried to take a picture edge-ways to show how thin the iPhone is, but the Treo camera is a crappy low resolution one and the iPhone is so thin it effectively disappeared in the photo.
