If you haven't heard, Microsoft is holding an event specifically geared towards Office and SharePoint developers.  It is being held February 10-13th in San Jose, California.  There are six different tracks and tons of excellent sessions lined up as well as an opening keynote from Bill Gates.

You can learn more about the conference here:  http://www.odc2008.com/

I'll be there, but I'm still trying to decide which sessions I'll be at.  Let me know if you're planning on attending or if you have any suggestions for tracks/sessions!
