Here is a cool product from the Launch Conference. A few months ago, my iPhone fell out of my bike jersey pocket at 20mph with only a slim plastic case and a ziploc for protection (more here). I have looked at Otterbox cases, but they are bulky. This case is waterproof, can be dropped from 6 feet up, and is just slightly thicker than a normal case. At $70, it is targeting a narrow market, but I will get one.
