I was never as bad as the average user.
I think it was three days in my first job when I was promoted to network and hardware guru for SGI, Sun and PC hardware.
It all just seemed so bloody logical and easy to setup.
Now accounts and HR completely different story. I suspect to this day they still think that their files are completely secure on the network and only they have access to them.
If I had shares in MS just now I would be thinking about selling them I suspect there is going to be a major change in the market over this issue and its not going to be pleasant for them. And I don't think apple are going to reap the benefits either.
