Are you lost at PAX? Or maybe you're at PAX and not used to being around so many people, and desperately looking for an excuse to stare at your iPhone for a while? Our social skills and sense of direction are poor enough that we've been in both predicaments.
ExpoJunkie just sent over a link to an iPhone/Android/Pre webapp designed just for the conference, with maps, and event listings by day and location. Best of all, ExpoJunkie PAX 09 edition is downloadable, so you can load it once and not be beholden to the whims of AT&T's crowded network or convention wi-fi.
Dear ESA -- dear everybody -- this is what we need for E3 and all other events where there are places to go and people to avoid.
