I bought an OEM version of Microsoft Office 2010 online and for me, the difference was that I did not receive a disc as such but was given a link instead where I downloaded the software. It was a legal download and I was given the registration key for the installation and I have it on my computer without any problem, in fact I put the software on a disc myself for future use.
