Office 2007 Beta 2 was released today.... You can get it here http://www.microsoft.com/office/preview/beta/getthebeta.mspx
I have downloaded it (when i could finally get in, System was overloaded...) and installed, looks great and works just as well. The only problem i have had with it is the Product activation (keeps telling me there is no Internet connection) but i assume that this is also due to overload. Now i just have to get around to installing Vista, of which beta 2 was also released today, along with beta 2 of longhorn server (which i also plan to install at some point).
