Apple added a new page to their iPad section called "Life on iPad".
Alongside the video that was shown at the iPad event on October 22, the site features six completely different profiles of people using the iPad for their professional work.
Of course the video and profiles show some extreme cases, but wouldn't you love to see yourself using the iPad the same way they do? I think this site should be seen as an inspiration what can actually be done on such a device if you're willing to do it.
Anyway, the message to take away here is that you are not bound to your computer anymore, with the right tools you can achieve a lot on those small and portable devices.
