Scosche wants to remedy this problem for your iProducts with a retractable iPhone/iPod charger called the Recoil. The Recoil has a magnetic docking mechanism that pulls the extendable cable back when not in use.
Scosche may want to think about knocking a few bucks off the $30 price tag, though, because some of us would rather have the unsightly wire and some extra cash in our pockets.
