"Mobile" sites are, more often than not, more annoying than helpful. If I've got a full browser in my phone, the right thing to do is almost always just to show me the regular site.<p>If you've got feature parity with your regular site and all those features work as well on my particular phone as they would if I was on the regular site, AND there's a good reason for the site to need to be changed to fit a small screen with a touch interface, then, fine, show me the mobile version.
