InVoca Voice-Activated Remote Control
Back in my day, I was the remote control -- "Hey! You! Change the channel! Turn that down! Turn that off!" Now, you no longer need to do the dirty work of technology when you can make it work for you. Talk to this remote control, and it'll follow your commands. Hopefully you can also ask it where it is, and it'll tell you that too.
A great dock especially if you like to plug your iphone into a speaker system or your TV. Includes a remote to change tracks or increase volume!
A water resistant ipod speaker case that attaches to your bicycle frame. There is also a handlebar remote control so you can chose what you want to be listening to.
