The Office I installed Office 12 a few days ago, well Beta 1, and it's not bad. Not bad at all. The obvious things like the update UI look great, I think the ribbon bars are a top idea. Outlook which looked pretty good anyway has been tweaked and had a bunch usability shortcuts added. The LCS integration is already in place and when the WSS and SPS bits are finished it'll be very impressive. Yep...being beta it suffers from some of the usual undocumented features that litter beta software but I'm happy enough with it not to go back to Office 2003.
