I think you are on the right track...in all seriousness you could use the keyboard lights as a form of feedback. For example, say you get a new email: Not only will the sound play but the keyboard will blink twice. Also useful if in case you are deaf and can't hear sound. Maybe a "message waiting" blink that could be noticed from across the room would help people just like when the light blinks on a telephone ring. Take a lesson from the Sidekick/hiptop!
