> I think it makes a good case study.
The only problem is that your case study does not accounts any potential losses which may occur if system update interrupts me and my job or whatever else. And if someone willing to obtain even more backslash than Vista and MS from users for harming their privacy and freedom of choice, annoyance, etc - that's right way to go.
From another side there is nothing wrong if updates are automatically installed by default so non-aware users are updated. But there should be override and choice anyway so I can regain my power to make decisions. Or it will be considered as atempt to FORCE me to do something against my wishes. This is unacceptable and called "slavery" btw. It's my computer for me. Not I am for my computer...
