Linux OS question

[SimonJ]

That so? Well then... I guess I'll put the full force of our company's support behind this team.

As far as the original post's question... if it's an older computer, I'd suggest something like Damn Small Linux or... Ubuntu with a simplified interface, such as LightDM.

LightDM is a display manager, not a desktop environment, hence the DM. As previously suggested Xfce would be a good idea, or #! for really old stuff.
