i thought the same of hands free cell phones... and I found people all day long with headphones, sometimes listening music, sometimes just in case the phione rings.
On a second thought. Some people already use glasses all day long. It would be great for most of them to have a little display with the current time, mail status, incoming calls, and along... At least, for me sounds nice.
