How many computers can Microsoft Office 2010 be installed on?

Below is an excerpt from Microsoft on Office 2007, which I would assume is a similar policy to what would've been used on 2003. "Microsoft Office Home and Student 2007 Retail License Terms allow for installation on three devices. OEM License Terms limit the installation to the device on which the software was pre-installed. Read the Microsoft Software License Terms (MSLT) for the 2007 Microsoft Office system."
