Despite all things that virtual provides, people still like the concrete, something to touch. Kinkos should offer a service that allows users to publish their blogs via dead-tree format.
I think with the advent of new materials that can change their shape and texture with electronic signals, it’ll usher in an age of computing where you can make the virtual quite real and disposable.
Imagine a material that you can alter the shape of through electronic signals. Then, you can change the shape to a spoon, and then later change it to a fork–you can even change it to be a back scratcher. Although that’s a very contrived and useless example, it illustrates reuse of physical objects in different functions, and even in different contexts.
