So, before I start waving my hands in the air, running around the office and 
panicking, does this mean that the user can not save files where ever he/she 
wants to on the HD in future versions of the Mac OS?

Sometimes, the user does.

If sandboxing ALLOWS the user to save in a private special place but PREVENTS 
them saving files where they choose, then this is a scary path.

I certainly hope this is not the case.

In all of Apple's success, I see the openness and fun to use nature of the Mac 
platform running away right in front of us.
