Small enough to fit in a pocket, but large enough for a decent-sized screen (see size comparison photo below).- Sharp screen, viewable at extreme angles.- Headphone jack is on the bottom, where (IMHO) it belongs.- Intuitive interface.- Quick return to top menu by pressing and holding the back button for about a half second.- Quick return to now-playing screen from anywhere

Sound and build quality are great, the screen is beautiful, and I have no complaints so far

The screen is easy to read and the manual buttons make the machine easy to control when I'm on my walks
