Office 2010 (For Windows) and Office 2011 (For Mac). This is the most recent version of Microsoft Office released. Most of the interface is the same as 2007/2008 and most common problems can be resolved the same way as they were in Office 2007/2008 and even Office 2003/2004. It's a good idea to know what version you're dealing with.
Office 2013
Designed for touchscreens and low-power devices.
Office 365
A subscription-based version of Office with cloud storage.
