I'm now at the same crossroads that nomis5 faced. I just deployed a mini-site after redesigning the client's primary site for responsive design. I set the mini-site at a fixed width for now. The primary site functions well on smartphones (iPhone and Androids), but it just wouldn't squish down to 320px - which leads to a couple of questions.

1) How do I best redirect just the feature phones to the mini-site or all mobiles?
2) Should I redirect non-mobiles back to the primary site or is the <link rel="alternate"> sufficient?

The client is a service business which makes mobile users an important target market, so I want to be as smart as I can here. I can live with sending smartphones to the mini-site, despite its limited visual appeal, in order to maximize the effectiveness. And should the day come when feature phones are no longer significant, I can always shut down the mini-site and take advantage of my work on the responsive aspects. But I've gone over Google's advice several times and it hasn't answered these questions for me.
