North Hall is a strange beast. There is no connection between South Hall, where the main action is, and North Hall (which is physically located accros the street), so you have to walk (gasp!) through a long tunnel like hallway to reach it. And then, you're into WeirdLand.
North Hall is where they hide dirty and shameful secrets, companies offering wacky products, like a mechanical speaker/megaphone for iPod, a church-oriented "worship presentation software"(does it run on the Jesus Phone?) or hand-made fine felt fabric MacBook and iPod sleeves, straight from the 60s...
But then North Hall has also some pretty big players, some with giant booths, like Acura (apart from the fact that they compare themselves to Apple on posters, what's the link with MacWorld?) and some with tiny floorspace, like IBM and Netgear.
An interesting thing in North Hall is the pretty large number of iPhone apps developpers, like Polar Bear Farm, Mobile Warrior or Appigo.
North Hall also hosts Aperture training sessions, live music and empty spaces. And the Electronic Fronteer Foundation.
So, be careful, if you're not nice, you might end up exiled to North Hall Hell.
