Anyone can now download the beta of Office 2010 at http://office.com/beta. It includes Word, PowerPoint, Outlook, Excel, OneNote, Access, Publisher, InfoPath, SharePoint Workspace, and Communicator! Microsoft suggests downloading it on a secondary PC. Remember that betas, even a thoroughly tested one like this, can crash and have bugs. Both 32-bit and 64-bit versions are available. You’ll find more information on the download site.
