Sony did the usable touch screen first on their camcorders.
Back then I looked at the Sony camcorder touchscreen, the flip phone with cameras, and the iPod, and told a coworker I wasn't going to buy any of them until it was all combined into one device with a full size touchscreen ... with the ability to play movies as well. And I told him most likely someone would dedign this because it was entirely possible, and it was the logical path to take.
6 years later the iPhone was born. He asked me how the hell I knew it would go that direction. I told him I didn't know. It just seemed like the logical thing to do.
