I use 2, both digital.

A Casio Exilim S880. It's thin, has lots of features and is easy to use (all features I can appreciate after slugging SLRs for years)

I also have a super cheap Samsung 4MP model (forget the model number). It's practically disposable and runs on AAs. Perfect for in a canoe, fishing, or anywhere else I'd rather not lose or destroy a few hundred dollars worth of camera.

My next purchase will be one of the freeze/drop/water proof models that are out there because the more I spend on something the rougher I seem to end up treating it.
