Windows 7 is more like Windows XP/Vista than Windows 8 is so it is more likely easier to just drop them back to what they probably already know.
Also Windows 8 is brand new and while it works just fine upgrading to it isn't really something that needs too be done just yet. Windows 7 is still a great OS.
