If we think about the user of the computer, the main feature is making it much easier and less complicated to customize the way the computer or the software application works. And I think we already see this in Web 2.0 and things like Facebook. They give really an enormous and unprecedented amount of flexibility to the end-user to customize the way those things look, the way they work, the way they interact with other programs. Not so long ago, if you had tried to do that you really needed a degree in computer science. Yet kids, everyone can use something like Facebook. What that shows us is that there is a way to make computing much more natural, to hide the technology from the actual functioning of the technology. I think that in the end will probably be the central feature of this new model.
