Stories from Eshibinga Primary I: Why Sugar?

A great stories from Eshibinga, Kenya, last year:

In April Mr. Juma came to Eshibinga to teach us on how to use an xo laptop. His teaching is helping us now. We got two new computers today. Then our teacher Mr. Peter told us to remember some of the things we were taught.

I just remembered one word. Sugar. We were told that sugar is the operating system for the XO. It organizes the systems that run the clock, activates the Activities, and store the Journal entries. The Terminal Activity runs text-based commands for your XO instead of the Sugar graphical commands.

What nobody has told us is , why did they name it sugar? Why not give it a name like coffee, or milk or water?

Please tell me?
