You can try the Windows 8 look-and-feel preview of Office free until it ships in 2013
Office 2013 Customer Preview ready to download
After weeks of anticipation, Microsoft has released a Customer Preview of the next MS Office, called Office 2013.
The Office 2013 Customer Preview is free, looks like and integrates with Windows 8 Metro, and makes Office more of a Cloud application than ever before.
The Windows 8 integration is big, of course, since Windows 8 is expected to launch in October and will become the dominant operating system for computes in the next few years. I predict Windows 8 will be on half a billion computers by the end of 2013.
