Yes, exactly. For example, my amplifier has an equalizer that has several modes. To switch modes, you press one button, and it cycles between them. The display shows what mode the amplifier just switched to. However, if I forget what mode I was previously in, I now have no idea what point in the cycle I'm at. Pressing the button just keeps cycling through the available options, round and round and round, with no indication when it's been through each option, and has started the cycle again. So, even if I know that the modes are in order: off, movie, music, concert, and custom, if I have no idea what mode the amplifier is in currently, I can't tell what mode is going to come next. I can usually figure it out by listening carefully, but it's still really annoying. The amp also has all kinds of settings, to due with everything from volume shaping to surround sound setup, and all of them must be changed through a menu. As I can't see the display, I can't tell what option I'm on in the menu, or what that option is set to. That's why I love my Sonos system so deeply. With Sonos, every setting is available in the fully accessible IOS app,. The Sonos speakers themselves only have 3 buttons, and no display at all. Nice and easy!
