The rubber coating does help with shock resistance. It'll protect the stick when it drops on the floor or hey, even water. Man, companies and their need for product branding these days.
There .. much better ;)
The Corsair Flash Voyager measures 75mm x 24mm (at its widest) x 15mm. The rubber casing does make the drive a lot more durable than the average plastic USB key, but it also attracts a lot of dust and dirt. We use a cloth to make our photo's on and the casing was smeared with little white fibers.
There is a small blue activity LED at the end of the drive (to the right of the "R" from Voyager), and when the device is being accessed, shines a bright blue in color.
