In this day and age, Linux is becoming a bigger player in the OS field. Not only that, the use of multiple forms of operating systems of all kinds is going on all around them: in iPhones, iPads, computers - both PCs and Macs - and students need to be familiar with other operating systems if they want to continue on in the IT field. This lesson exposes them to a form of Linux that is used on PCs and students need to lose their fear of the unknown - in this case, Linux OS, and play with more than just one OS to compare and contrast them. Ubuntu is perfect because it can be loaded onto an older, more common computer usually found in computer repair classrooms and will very little or no cost. The fact that linux is open source and 'free' is something that can also be discussed during the time students are installing the operating systems.
