The addition of a usable keyboard potentially enables all kinds of interesting new mobile applications, but few compelling apps are being written (to my knowledge), much less open source apps.

It’s not a lack of tools: Research in Motion has an easy-to-use SDK for authoring Blackberry apps in Java; I’m sure other smart phones have similar environments.

Maybe geeks can’t afford Blackberry’s and smart phones. But if there is anyone interested in collaborating on Berry 411 and projects like it, please let me know; I plan to release the source.
