One of the new technologies to debut at PDC, providing attendees the first glimpses is that of Office 12.  I recall talk about Office 12 from my days in Microsoft Consulting Services a few years back, how it was going to be a complete rewrite from the ground up, eliminating any remnant of 16-bit code, etc.  Well, I can definitely vouch for the overhauled user experience - it looks NOTHING like its predecessors.  I am absolutely looking forward to giving it a whirl when it's available!
