Although I absolutely love the idea of not having to tend the hardware or Windows anymore, I'm still very aware of both and the things that can go wrong as well as the problems having to do with security. In that vein, nothing will convince me to use the Cloud because I don't know the people who are tending to that whereas I do know the people in my company. And, yes... I still know how to make the necessary changes in an emergency where I'd have to wait for some person in the Cloud to decide to work on my help-desk ticket request.
