I'm surprised it didn't happen sooner, but Canon has finally decided to enter the market for rugged point-and-shoot cameras. It's kind of odd looking--I think it looks like a submarine--but according to the company the PowerShot D10 is freezeproof down to down to 14 degrees, shockproof up to a 4-foot drop and submersible up to 33 feet. Canon will offer interchangeable face plates and other accessories to match the camera to your adventure outfit du jour.
On a more prosaic note, the D10 has a 12-megapixel CCD, 3X zoom lens and all the automation features bestowed by the company's Digic 4 processor. Though it's one of the few PowerShots that doesn't bear "IS" in the name, it nevertheless has optical image stabilization. It will cost a competitive $329.99 when it ships in early May, too late for me to subject it to a NYC winter. I guess I'll just have to take a beach vacation to test it.
