Windows Azure, Google and the Cloud

Windows has given a sneel peek into the Azure which is based on the Cloud concept. The Cloud gives us the ability to access our data from anywhere. This has been one the main arguments in favour of the Cloud. This offcourse carries the risk of having to accept the data being hosted elsewhere and not inhouse both for enterprises and as individual personal use.

If storage costs are falling rapidly and the access to broad band is increasing at a random pace, why then can not enterprises have thier own mini cloud and personal users be able to setup a server with enough storage capacity and be able to access that from anywhere?

Is this the big corporates trying to push solutions on us? What ever it is, it would be very intresting to see how this develops in the next five years to ten years.
