I had the chance to take a look at Otterbox's Defender case for the BlackBerry Storm a few months ago. I was impressed with OtterBox's durability but did have a short list of issues. As it turns out they just released a new BlackBerry Storm case called the Commuter. From looking at the PR on the case it looks like they addressed the issues I had with the Defender. Because of that I was excited to put my Defender away and give the Commuter a try.
