Sansa Fuze and fast/forward on audiobooks and podcast

The Sansa Fuze allows you to seek using the left and right sides of the scroll wheel.  As you hold the wheel down, it skips by increasingly larger increments.  This works rather well and is, in my opinion, almost the right way of accomplishing this.  Personally, I would prefer what I believe you are describing, which is to run my finger in circles around the scroll wheel in order to seek.
