Give the gift of Ubuntu this Christmas! Download a CD image, burn a few copies, and stuff them in your favorite geek’s stocking this year. Once the joy of trying on new sweaters wears off, they can pop in the LiveCD and try Ubuntu without making any changes to their computer.
An Ubuntu LiveCD (or even better, Ubuntu on a bootable flash drive) is also great for college students who may not want to leave their personal information all over campus. They can pop the CD or flash drive into any public computer, and they can check email or browse the web without leaving tracks.
