i think it would be a good idea. i think this because if you are looking at things on your computer and you dont want your parents to see you can just put it in then takeitout when your done and your parents wont know what you were doing on the computer. they wont even have proof you were on there. i think it would be a bad idea because it runs a lot slower then a regular a regular operating system. But over all its a good idea to put an operating system on a cd-rom or a USB device.

I agree with you. It is a way around people watching you. It is useful. Also it is a lot slower.
