Is it enough bandwidth to stream audio from shoutcast?

If not, maybe it could send map data for gps?

You could have a simple read-only imap email client running.

GPS combined with a thin web client for movie listings/restaurants in your area.

You could probably use GPS and this to send your coordinates to a web server somewhere, and retrieve a map periodically for display.

Use it as a poorman's lojack, ala Kim Salo.

Text streaming of the unofficial BBS, of course.
