Insert thought: for conferences, I really like the small form-factor of the Lenovo X61 Tablet. I'm sure my seatmates appreciate it, too.
I plan to switch to OneNote 2007 as my note-taking tool. I like the interface of a notebook and pages on which to take notes. Note to self: bring an external mic so that I can record sessions in OneNote for review. So, after the break, I'll resume in OneNote 2007 but still in laptop mode and see how it goes.
