While personally I use the computer as entertainment I
also see where many places, especially in the work environment, where
employers don't even allow entertainment on the computers period.

To me a cloud is a soultion in search of a problem. Same/backup/whatever on
another HD, flash drive, something like that. For those users in locations
that are somewhat of a distance from one another use a server in one or the
other or both locations. This way they still have complete control how the
data is archived and shared and used. They are not at the mercy of some big
company to provide that support, only the communications between the
locations.

When companies like Sony, Google, credit card companies and others let your
user personal info out. What about the smaller cloud companies. The solution
is keep all unnecessary info in-house letting out only that is necessary. In
the service when it came to secret information the policy was "do you have a
need to know'". While I helped maintain the security system on the nuclear
weapons on board ship I never knew if they were on board or not. I'm sure
that when we were on line in Viet Nam nucks were not present but I'm not
sure.
