I want to point your attention to our new conference on Mobile Experience Design & Usability ... called MobX (http://mobxcon.org).
Yeah, I know - Barcelona-Berlin is not exactly around the corner :) But hey: it's still Europe, right? We have invited super interesting speakers from Uganda, Australia, USA ... and they all come to join us in Berlin on Nov 18, 2011 (workshops on Nov 17) for an awesome one day high speed conference.
It would be super nice to meet some spanish UX experts at our conference as well.
If you have any questions, plz feel free to ping me.
