I cannot stand using mutiple remotes in one home. Imagine having over 20 devices in a home and having a seperate remote for each one that could get pretty time consuming. Thats why I checked out RedEyE, it lets you stick the infrared unit in the earphone jack. there fore you could have your device on a charger while using it.
