Forgive me for being too blatant, but I'm puzzled by their reason of doing this. Do people really switch search engines because of the UI? I understand that some people might prefer the less cluttered version, but when it comes down to it, the way it looks is secondary to its primary function: giving you good results. After a while, the look becomes less important.
I don't think it also serves their interest well, too, when their UI is a reminder of their competitor (the retro look of their competitor, to be precise). Google succeeded with a minimalistic UI because it made them look different from the rest and no one did it before. When Bing does it now, it makes them look like Google.
