The news post in the Inquirer is labeled as "Nokia 770 finally gets useful" (after getting navigation software)

That story made me to think usefulness of the device. I think it is useful. Here are some not so hard to figure:

- Previewing & deleting photos taken with camera phone.
- Self education by reading old books from gutenberg.org
- gaming while waiting for a date
- Blogging

Let's try to find real, not so obvious, uses for the device. Please also include ideas that you think it could be used but is not yet.
