Hehehe, I hope this is the right forum. I am surprised there isn't a "Webdesign for Mobile" forum as important as mobile has gotten. Hint, hint suggestion.

At any rate. This is just a general question, but if you are working with a web application framework/ platform, would you prefer to have the basis laid out simply for responsive design in the templating system, or would you rather have a supplementary mobile framework available within the platform like jQuery Mobile or Sencha Touch, so you can actually create much more compelling mobile versions of your web application/ site? I realize this goes along with how much experience you have, but let's say you are very experienced, what would you consider the better choice?
