Here's a neat event from Microsoft is coming up in the new year:
VANCOUVER: Microsoft User Group: An Introduction to the Windows x64 Editions
January 12, 2006 6:30 PM - January 12, 2006 8:30 PM (GMT-08:00) Pacific Time (US & Canada)
Welcome Time: 6:00 PM
I'm not that familiar with the 64 bit editions so I'm probably going to check it out. Sounds cool.
