The software is offered as a free ISO CD image download of around 700MB. I you have a really slow internet connection, however, you can get the CD for only $7.97. Here is the description from the Ubuntu CE website:

You can view screenshots of Ubuntu CE here. I like that it offers OpenOffice, which I use all the time anyway. But I would definitely get rid of or not install the Virtual Rosary!
