If you do that you have to double the used web space, and that can be expensive. I'm already almost at the upper limit for my site and will have to go to the next tier of hosting soon. As it is, only three of the well over a hundred pages on my site need a special mobile version, and I would imagine a lot of other folks are the same way.
Having it first look for m.sitename, falling back to mobile.html if it exists and m.sitename doesn't, then index.html if there are neither m.sitename or mobile.html might be a good idea, though.
