Controls
The scroll wheel of the iPod Video/iPod Classic can be a little bit hard to master. Until you get the hang of it, you may overshoot your targets. Also, the screen on this model is smaller than that of the Zune by a small amount.
As for the Zune, the buttons have only a little bit of space between them, and it is easy to inadvertently turn the volume up when you are trying to forward a song. In addition, while the screen is larger than that of the iPod Video, its resolution is lower. The Zune's screen is smaller than an iPod Touch.
While the control sensitivity issue is a problem for both the Zune and the iPod Video, the majority of iPod models have no control problems to speak of. So, we'll declare iPod the clear victor in this subsection of device design.
Weight
In this case the Shuffle is out of the running, and we'll only compare video playing-models. The Zune is heavier than the Nano, but lighter than the Touch or Classic by a small amount so Zune wins this category.
Aesthetics
The iPod has sleek, rounded corners while the Zune favors squared-off edges. However, the iPod is going to take this design category for one simple reason - they are distinct from a distance. You could easily mistake a Zune for another MP3 player or device, but the same is not true for an iPod. For standing out in the electronic crowd, the conceptual design award belongs to iPod.
At 2 to 1, the iPod's have won the device design category, and that now makes the overall tally at the end of round two: iPod-2 Zune-0.
