After losing his iPod Touch when it slipped out of his pocket in a cab, skater Sean Bonner decided to make his iPod easier to hold onto.
I started thinking about about things I've owned in the past that I didn't lose, and which ones of those were definitely not slippery. The answer was immediately obvious. A skateboard.
He purchased a length of black grip tape and covered the back of his new iPod with it. So far, it hasn't moved.
