The Office 2013 changes mean that FPP has gone
The only reasonably flexible option is volume licensing which is (AFAIK) only available for 5+ licenses. That's not a problem for the business I work in where we have over 20 PCs but for a home user or micro business with 2 or 3 PCs it's useless. With Office 2013 FPP has effectively been abolished making all that can be purchased outside the volume licensing channel is either one that is like OEM on previous versions or the subscription-based Office365.
In addition the restrictions on transferring the OEM-style licenses seem to have been tightened to only allow transfers where the computer is replaced under warranty rather that effectively any breakdown replacement.
None of this is good news. Although I still use Office 2000 on my own computer at home I am unlikely to install any version of Office on the next computer I own.
