As you might expect, the North Hall is a little less crowded and there doesn't tend to be the same large clumps of people trying to squeeze into booths--the Apple booth, by comparison, often looks like some sort of very geeky mass wrestling match.
There are exceptions that prove the rule though, and is one such exception. As I was walking around the North Hall looking for neat things to write about (I do it for you, dear readers, all for you!) I was stopped in my tracks by a press of humanity all eagerly waiting to see a in action.
The Pulse Smartpen, in case you're unfamiliar, lets you sync your written notes to your Mac thanks to their . The pen also records audio as you write, allowing you to tap on some text that you wrote and play back the audio that was recorded while you wrote it (you do have to use special mircodot paper to enable all this magic though). That's just the tip of the iceberg with the Pulse Smartpen, which is why I am not shocked that so many people wanted to see a demo in person--plus it won a so you know it's got to be good.
The LiveScribe booth really livens up the North Hall, and I recommend you check it out if you're at Expo.
