I like the point of this post, but I wish the author would have elaborated more. Sanitary URLs are great because they play on human emotions. Looking at the simple, clean Apple URL, it does two things: it provides an easy to remember route to their specific product, and two, it feels <i>clean</i>. In contrast, the Sony URL feels dirty and disorganized, lacking a real focus and seemingly, makes the Walkmen feel like just another electronic whatchamacalit. Although it seems purely cosmetic, there's a subconscious thing going on. Yes it helps developers/consumers but even more importantly, it makes your brand look focused. There should be more writing on the psych aspects of web development. I feel like there's a lot to be said.
