I am always on the lookout for the perfect case, and depending on the day's events, I might swap cases once or more during the day. For example, this week I chaperoned for my daughter's Field Trip. This was no visit to a quiet, cozy museum but rather an outdoor hike and 'Stream Study', in a muddy park. And it was raining. Fortunately, I had the Kraken case from Trident ($34.95). While the Kraken is not billed as being waterproof, the case has rubber flaps that cover the various openings such as the dock connector and audio jack. The camera and front glass are covered by clear durable film as well, making it dust resistant.
