SharePoint 2010 BETA available
Microsoft made a number of announcements at or around PDC this year including some big ones relating to Microsoft Office and Microsoft SharePoint 2010. As you may already know, the “Office” has been removed from SharePoint’s official title; which is now simply Microsoft SharePoint Server 2010. This means the MOSS acronym doesn’t work anymore. But don’t start using MSS since that acronym is used by Microsoft Search Server. SharePoint is just SharePoint.
SharePoint 2010 BETA is now available and can be downloaded here. Many of the developer tools in SharePoint have been greatly enhanced to promote increase productivity. A formal list of benefits can be found here or another good list is on Arpan Shah's blog.
What started out as a leak was later confirmed by Microsoft; the official RTM month for Microsoft Office 2010 is next June. One can only extrapolate that with the tight integration between Microsoft Office and Microsoft SharePoint that both will release at roughly the same time.
So... if you are someone that has Office 2003 should you wait until June to upgrade? Microsoft doesn't think so and is offering some enticing promotions to get you to upgrade sooner rather than later.
Or, if you're like me, you download the BETA and just use that
