The Kindle has a built in cell receiver so that you can wirelessly browse, preview and purchase books using one-click.
Being at home on a rainy day, but wanting to read some new novel that just came out, you can have it in seconds. This concept (not hobbled by DRM) is pretty damned liberating.
Plenty of free e-books in Mobipocket format show up fine on Kindle.
