On the other hand, I have thought about going silver, simply because I can walk down the street and buy it no problem for $269 every day, and then putting a skin on it like this:

In that way I can pick, or change, the color at will. As for the ease of returning the silver locally, I intend to buy a colored one from walmart.com's website, have it shipped to my local store and pick up. If I don't like it I can just return it to the store. Whatever color I go with I can easily return it.
