I guess it's just my age, but I am not so crazy about the whole cloud thing. My first computer was an Apple ][ in 1978. This was the the beginning of the personal computer revolution that was supposed to liberate us from the computer center mainframe "priesthood".
It seems really ironic that we have come full circle to the point where Apple is now the world's largest corporation and wants your entire digital life on their servers. That would have been crazy science fiction in 1978. It really puts the famous Ridley Scott TV commercial into a different context.
