I did mention it and it is the 880. A receiver and multiple components is the reason. Most receiver remotes don't have an Appletv and Roku button ( as two examples), so you also have to remember that the CD button is for Appletv and the TV button is for Roku ( as two common examples).I honestly can't understand why anyone would struggle with multiple remotes as many of you suggest. You know the TV remote turns the TV on (CEC disabled on all products BTW) and the PVR remotes turn the PVR on etc. etc. The only thing you have to remember is which HDMI input is for which devices. Once you can remember that then controlling the individual devices is child's play.
Incidentally QuarterSwede and Uofmtiger neither of you have said which Harmony models you are using.
If you don't have much in your setup, you can get by with a couple remotes. However, 7 remotes would be more than enough to get me to buy a universal.
