The first time I wanted to serve my mobile users, I went the way of putting mobile content on a subdomain. Almost immediately had issues with indexing; in some cases the m.example.com was indexed, in others it was not, it kind of went back and forth and was a nuisance.
Now I'm all about detecting the browser and redirection, and that seems to work a lot better. The users have an option to view the full site if they want to. My mobile users get a shortened menu.
Since many of my sites are monetized, I still have to deal with that issue before I go full responsive, though. I also want to test what effect that might have on mobile revenue; after a couple years I have a pretty good idea of what I can expect now. Curious if responsive design will affect that.
(I think the default twenty eleven theme that comes with WordPress is now responsive out of the box)
