"Cloud Computing"

I had never heard of "Cloud Computing" before and I found it very interesting. It is truly amazing how computers have revolutionized how we do things. I watched the "Cloud Computing in Plain English" video and found it to be quite helpful. I use Wikipedia so I guess I have been using "Cloud Computing" without knowing it. I read the article by Chris Peters called, "What is Cloud Computing and How will it Affect Libraries?" I liked his honest answer when he said, "I don't know and neither does anyone else." I guess I could see it being very useful for libraries to use it for OPAC, email, and possibly ILLs. I would have to be very assured that it is a safe -- secure way to go.
