Microsoft Office 2010 Beta Download
The Microsoft Office 2010 Beta can be downloaded for free. I have been using it for a few days now and while it doesn't look dramatically different--it will be worth getting when it is released later (June) this year. And the "File" menu is back! My only advice when you install it is that you don't "upgrade" but instead keep your existing Office 2007 software installed. Get it here.
