PAX East 2011? There's an app for that. Proxima Labs' Conventionist, an app designed expressly for staying organized during conventions, has been updated with a guide to PAX East's panels, exhibitors and pretty much anything you'd need to know about the show.
The app for free for iOS and Android, and has some handy features, such as reminder messages (so you don't miss panels) and maps (so you know where they'll be). It sounds pretty indispensable. Might we suggest adding the Joystiq Blueberry Muffin Tops Breakfast once you've downloaded it?
