If the Otterbox Defender is like full plate armor when it comes to iPhone protection, and the Commuter is plate mail, then the newly announced Reflex is easy on, easy off, ultra modern kevlar.

Rather than layers of soft silicone and hard plastic, Reflex is a two part plastic shell that slides off when you want to dock and slides back on when you're ready rock.

We got a look at it live at CES 2011, so check out the video and let us know what you think -- old school Defender or new school Reflex?
