There are so many options once Dropbox can theoritcally be accessed through an inbox interface...

Mailbox could be a first step to competing with Messages/gChat. Instead of rolling out their own email, Dropbox can be another type of account Mailbox works with to send pictures, videos, files over data rather than texting or emailing. An odd feature to roll out without acquiring a popular product, but making Dropbox the goto rather than the link attached to something else.

Why should Dropbox have a message client (or email client). I fail to see how they are connected. I feel the same about Twitter launching a music service.

There used to be the joke that every software expands until it can read mail. Nowadays I think we need a new saying. Every software company expands until... it has rebuilt every other software product (not as catchy).

Not messaging per-se exactly, but making Dropbox an account that could be accessed through Mailbox. The standalone messaging without sending a file as well is just a wacky idea of a different direction Dropbox could decide to take things.

How about:

"Every software company expands until it has implemented half of Emacs."

Sort of a product-centric version of Greenspun's rule.
