Office 2007 has RTM'd today, and this includes Microsoft Office SharePoint Server 2007.
This is great timing, with Grant Paisley coming to Adelaide to give his talk about integrating BI and MOSS. This is a great talk, and if you're going to be in Adelaide, you should be there! Go to sqlserver.org.au, and find the link. And if you can't make it in Adelaide, go to his session in Canberra instead! I heard it at the SQL Code Camp, and it's definitely worth checking out.
The great thing about Office 2007 with BI stuff is that BI is all about making the data you have more useful. And Office 2007 is so much better integrated with other systems than previous versions, so it can become a great portal to getting your information out there.
