Apple's usually pretty when it comes to commercials. They keep it simple but show some of their standout Apps that make the iPad the kind of device you want to use regularly. That's whether its for music education, reading or anything else.
According to the commercial, Director David Fincher uses an iPad for a clapperboard app. That wouldn't surprise us as he's been known to use Final Cut Pro for editing.
If you take anything from the video though, it's just that Apple wants you to know that there are over 60,000 iPad Apps available on the App Store, and there's something for everybody.
