With Microsoft Office 2010 Home and Business you get Word, Excel, PowerPoint and Outlook.

However with the retail box you are permitted to install the software on your primary computer AND laptop.

Here is a quote from the Microsoft Office website “the retail license terms allow you to install, activate, and use Office Home and Business 2010 or Office Professional 2010 on your primary PC and your portable device such as your laptop. This license is for your use exclusively.”
