In the cloud

You make valid points. Another concern is the cost and availibilty of connection. If everyone went over to cloud, then everyone would be at the mercy of the internet providers and connections, and the way the governments around the would are trying to interfer with the running and freedom of the interent makes for concern. The saying "using technology for the sake of technology" is a dangerous way to go, where I prefer "if it ain't broke, don't fix it". Is there exsisting technology that can do the job? And do you NEED to do this? are 2 questions I ask before I change anything. Sometimes there is the idea of improvement and doing thing better and more efficiently, but at what cost and risk? and are the costs and ricks worth it?
Please don't get me wrong, it not that I don't like new things, I do like and imbrace new technology and new ideas, but I like to make sure it is for the right reasons?
