Apple Dock for iPod 3G (White)
considering the dock...
If you are considering the 15GB ipod you might as well get the 20GB ipod which gives you a dock.  This dock is about 38 dollars and the 15GB ipod is about 250 dollars which adds up to 288.  A 20GB ipod is 275 on amazon...so make good decision. But if you already have an ipod then u don't have to worry about the cost.  Just get the dock.
