DrupalCon Denver is a Matryoshka doll. Ostensibly a Drupal conference, hidden inside you'll find several smaller conferences. We call them "tracks," but they really are full conferences. You could show up at DrupalCon, attend only one track, and get more than you get at most single-topic conferences for a fraction of the price. As co-chair for the Mobile track at DrupalCon along with Todd Nienkerk, I've been involved with making sure we have the best possible sessions focused on mobile within the wider conference.
