"Like, say, being able to access any input in a multi-input device with just one press."
Some mini-hifi units do not have a button for "audio in" - so you have to find the remote control to use that function from six inches away.
The buttons on such units are also often victims to style over function. Grey or pale blue on black is hard to read in low light. Such a Sony amplifier from the charity shop took several minutes to discover how to switch it on. The decorative silver thin strip across the front had cunning pressure switches at its extreme ends for "on/off" and "CD tray eject". They were denoted by engraved colourless symbols that were only visible in good light at the right angle.
