A 24" touch-screen iPhone?

In honor of today’s launch of the iPhone 3G S… this video, which purports to show a demo of a hacked Mac running the iPhone operating system using a giant touch screen, is a hoax, but it’s still fun to watch:

The Unofficial Apple Weblog writes, “How’d they do it? It’s most likely just a movie running on a screen, with a guy pretending to control it. But even so, it’s a compelling idea — if you could find a multitouch monitor that worked like that and ran the iPhone OS with it, wouldn’t it work exactly that way anyway?”

And that’s one of the reasons why the video is so compelling: We’ll probably be interacting with our computers in a similar way within just a few years.
