Digitalcamerareview has taken a look at the 6MP WPi waterproof digicam from Pentax, here's a small snip from their full review:

Whether you're heading to the beach to escape the cold or hitting the ski slopes to enjoy some winter sport, you'll want to have a digital camera with you to capture the memories. What you don't want is ocean water or slushy wet snow getting into that digital camera you take and rendering it useless. A waterproof camera would be perfect in either scenario; enter the Pentax WPi 6.0 Megapixel camera -- designed to resist water and dust so that it's "lifeproof" and keeps on working in rain, snow, or dust storm!
