I have mixed feelings on the idea of sandboxed apps.
On the one hand, I want to be able to run untrusted applications safely. And in a larger sense, I think that it might be a hopeless endeavor to try to get users to only run trustworthy applications on their machines.
On the other hand, I want to have full access to my system, and sometimes that means having full access to it through applications (jbk's VLC use case is a good example of that). And sandboxes are far from perfect (this may improve, but right now existing sandboxes still have lots of holes). Sandboxes may be just security theater at this point (although as I said, this might change).
