Microsoft sparked a lot of anger when it suggested that you will be unable to play used games on the Xbox 720.
Now apparently for their 2013 Office suite, the license will be tied to ONLY the computer it is installed on. In other words if you pay for their office suite, and your computer crashes. You will have to pay AGAIN to get it on the new computer. You can no longer transfer the license to a new computer like with previous versions.
Now you might see people starting to move to other options.... OpenOffice? Google Docs? LibreOffice?
