Creative's Zen Vision has no fewer than 11 buttons that can be used during playback, two for volume, two for rewinding, three for forwarding, one for play/pause, one for turning an overlay on and off, and one to bring up a menu for screen size changes and seeking. In addition to its separate volume and brightness buttons, Sony's PlayStation Portable puts up a bewildering array of 14 icons on screen and leaves you to scroll, sort through and figure them out. Simple as they are, the iPod's stripped controls just work.
