The n Series is a Dell product line that does not ship with a pre-installed version of Microsoft Windows. Apparently prohibited from shipping computers with an operating system by an existing licensing agreement with Microsoft, Dell instead ships these systems with either the open-sourceFreeDOS operating system or the Ubuntu Linux distribution not preinstalled, but on install disks.
The company has come under fire for making the FreeDOS-powered machines no cheaper and more difficult to purchase than identical systems running Windows.
Dell also offers various Precision Workstations with Red Hat Enterprise Linux pre-installed. These, like all other products in the Precision series, are marketed at enterprises.
