On the main floor TV, I am running a small Pioneer AVR, and a 3.1 setup. Logitech remote, and the whole family can use it fine.
In the basement, I have a full 5.1 setup. Another Logitech remote there, and most functions are simple to use. Only the use of a streaming TV device warrants the use of an iPad as the remote for it, as it is simpler to navigate vs teaching the Logitech.
