According to The Verge, the next version of Microsoft Office (2013) will not run on Windows Vista or XP.

So, now there’s another good reason to avoid the latest version of Office, as if you needed one. Microsoft has struggled to get people to upgrade Office. Many users still run – and are perfectly happy with – much earlier versions. The general perception is that while new versions may look fancy, they tend to increase bloat, while randomly removing useful features, adding useless new features, introducing fun new bugs, and changing the user interface to make everything harder to find.

I predict that people will stay away from Office 2013 in even greater numbers than for previous versions.
