I've been wanting to replace my iPod Nanos for a few years now (they're 10 years old already, and the batteries are starting to go), but everything nowadays is touch-screen, and so completely unusable for me. Why? With that tactile single click-wheel, it was very easy for me to put the iPod in my pocket and not look at it for the entire flight, even when I wanted to skip the next song or replay or pause.
