On the lower half of the Samsung YP-Z5 sits a square touch-sensitive control that requires you to lay a fingertip gently on the top half for scrolling up or the lower half for scrolling down. Once the proper item is highlighted, you click the middle of the touch pad to select it. There's a slight lag before the cursor starts scrolling, and if you press too hard or softly, nothing happens. Furthermore, it'll take some dexterity to get your touch just right, and you'll often find yourself scrolling past the intended selection. After a few days of use, most people will get used to it, although it's clearly not as intuitive and easy to use as Apple's competing Click Wheel.
We appreciate the Samsung YP-Z5's dedicated buttons for back, fast-forward, rewind, and play/pause/power. They surround the touch pad while the dedicated volume buttons are placed on the side for easy access with the right thumb when the device is in your hand. With its dedicated volume and play/pause (more on this later) buttons, the YP-Z5 bests the iPod, which has neither. A handy hold switch on the top and a recessed reset button on the bottom round out the controls. You will notice two screws on either side of the player, and presumably, you can replace a dead battery yourself, though we wouldn't recommend it.
All of the Samsung YP-Z5's buttons feel solid, and the device's aluminum case is pleasantly cool to the touch. The YP-Z5's overall build quality appears to be quite high, and its screen is nowhere near as scratch-prone as the Nano's. We dragged a key right across it, and it didn't scratch until we pressed hard.
We should mention that the Samsung YP-Z5 utilizes a proprietary dock/USB port, much like the iPod Nano. There's no word yet on YP-Z5 accessories, though the unit ships with white earbuds, a proprietary USB connector, an installation disc, and a manual (both paper and electronic).
