Remember how disappointed TUAW readers were in the H2O Audio "waterproof" Nano housing that was, at best, water resistant? Today's Las Vegas-based Consumer Electronics Show brings better news. Here's a demonstration of an actual waterproof container for your iPod, courtesy of Atlantic's EGO waterproof sound case (PDF). Unfortunately, they've designed this for party goers rather than lap swimmers, but it's still a very nice step in the right direction. How hard do you think it would be to hear this thing in a shower? Pretty hard, I'd imagine. And does it look to you like it's built for rough handling or just to float and get occasionally splashed?
