Do users really need Windows applications in Chrome OS?

Am I the only one that views running Windows applications in Chrome OS with a dubious eye? I thought one of the big selling points of Chrome OS was that it was a lightweight operating system that freed people from the headaches associated with running Windows? So it seems self-defeating to me to even want to install Wine in Chrome OS.

It seems to me that at some point a user who stops using Windows as their main operating system also has to eventually cut the cord tethering them to Windows applications.
