Hello. We are constantly having to replace the handset cords on our phones. They get tangled and knotted up way more often then they should. I know it is the user, but if there were no cord, this wouldn't be an issue. I think it would be a great idea to have a cordless handset (bluetooth) on new phones. The handset can easily fit a battery. Two small contact points in the phone base and the handset can keep it charged when on hook. I am sure I am not the first person to think of this. Personally I would purchase a "cordless" phone over a corded.
Thanks!
