Using Ubuntu in my library

If I saw a way for using Ubuntu to cut costs in my library I would consider switching to Ubuntu's OS. The additional open source software that comes with Ubuntu is a great selling feature. There isn't usually money in a library budget to pay for software like Photoshop but having Gimp on the computers for free could increase customers who may be interested in doing some basic photo editing and would also open the possibility of offering classes for patrons on photo editing or audio editing.
