Cases are a personal preference thing. This doesn't offer 'equal' protection as an Otterbox Commuter in my eyes. This is my preference, but I prefer to have my ports covered and not exposed. I've dropped it a few times while strolling in the park with broken twigs and what not lying around. At least I know for sure it will keep macro particles away from the ports. Not so with the speakers and mic.
Even dropped it on my dog's business (she knocked it out of my hand)... cleaning that was fun...
