Microsoft Office Professional Plus 2010 Beta download

Microsoft offers downloads of its Microsoft Office Professional Plus 2010 Beta for free via this link. That's the best offer we've seen on this program. It includes Excel, PowerPoint, Word, Outlook, and more, for Windows XP, Vista, and 7.

Of note, this is pre-release software (it may be buggy) that will expire in the future (you may find yourself stuck into buying the paid version later).
