Everyone often raves about apple design. How sleek they look. How cool they look. However, there are sometimes practical design aspects that people complain about. Namely, I remember the first generation Nanos would have a faceplate that scratched easily.
However, I wonder if there is a side to the design that hadn't been considered. For a device like the iPod, it had the requirement of storing large amounts of data, but flash devices weren't that big in size yet. Therefore, hard drives were the only choice. However, we all know that electronics and especially hard drives are sensitive to shock. It would lose its performance and its ability to store data if it was knocked around all the time.
Whether it is intentional or a consequence of making it look sleek, the exterior of the iPod, and perhaps its vulnerability, leads people towards behavior that make them take care of it. They buy protective accessories for it, and I'm sure they throw it around less than their phones.
It would be brilliant if that was part of the requirements and spec: to get people to take care of their iPod by making it both sleek and vulnerable. It's much the same way (in function, not in emotion) that a certain instinct gets triggered when we see cute fuzzy things, except Apple managed it without fur or a large forehead.
