We've already talked about OtterBoxes before. And these really tough, pocket-bulging cases follow military specifications, meaning they're designed to protect a smartphone or PDA even under very hostile conditions. Despite the strong layers of protection however, an Otterbox still allows access to most of the gadget's functions. Think of it as a locked vault that lets you spend the money inside. Something like that.

Treo fans who want to guard their smartphone against abuse--for the right (going to a construction site) or wrong (using it as a baseball substitute) reasons, the recently announced Otterbox 1921 is the ruggedized case for you. Aside from providing drop, shock, water, and dust resistance, the Otterbox 1921 still lets you use the Treo's touch-screen, take pictures with the smartphone's camera, hear audio from its speaker, and of course, make full use of the QWERTY thumboard. All while the case is snugly shut.

So, if you're a new Treo owner and don't mind turning a portable smartphone into a bulky yet well-protected gadget, check out OtterBox.com. Even if you don't own a Treo, Otter Products Inc. (the manufacture) makes ruggedized cases for a variety of smartphones and PDAs.
