Wow, I've started to receive lots of emails already (and fortunately not a lot of SPAM).  Below are the first ideas that have come off the line (in no particular order):

• Colored Headphones
• Dual headphone jacks
• LCD remote
• Wi-Fi detector
• Boombox
• Wireless headphones
• In-car dock
• Ipod connector adapter
• Alarm clock
• Mini speakers
• Cup holder

The good news is that most of these are in the works in one form or another.  Keep the ideas coming!
