All this cloud stuff is basically down to this:
The US already had data on 3bn people on the planet, thank you ever so much, facebook, and was lacking data on businesses ... then, some smart ass came along and the following discussion took place:
Boffin: "Since we cannot hack each and every company network, why not centralize the data in controlled data centers. Let's use the might of US IT enterprises and call it 'The Cloud'"
Manager: "Yeah, but, nobody is stupid enough to put their data on your 'Cloud'"
Boffin: "Well, Microsoft has a 90% marketshare in client software, IT decision makers are as thick as rock!"
Manager: "Right, let's do that, then."
