Thanks to everyone so far for the input. I will definitely keep it in mind when making my purchase.
My wife has a waterproof camera carrier that she uses when we're taking pics in the outdoors. During inclement weather or near the surf, we take it out, shoot a pic, and put it back away in its waterproof holder. This has worked wonders on our regular cameras so far, so I'm hoping that it will be helpful in retarding any deterioration of a digital.
