Photojojo is now selling the Optrix iPhone Adventure Suit—a waterproof plastic housing designed to protect your iPhone and turn it into a go-anywhere underwater action-cam. I think the idea is wonderful—protecting your iPhone so that this one device can really do multiple things for you, including putting itself in harm’s way to get the pictures and videos—but at high price I wonder if it’s really worth the risk. After all, if your GoPro comes loose from its mounting and disappears to the depths of the ocean, you’re out a couple hundred bucks and whatever footage you shot that day. But when your iPhone goes missing, you’ve got an expensive and time problem on your hands. If you’re desperate to take your iPhone with you on a dive, this may be the solution. But if you lose your phone, don’t say I didn’t warn you.
