if you really knew how often how many companies out there had data breaches of personal information you wouldnt trust your own computer to remember its own password...
suffice it to say this the difference between this and the others is the 'high profile' nature of it... not that that makes anything better mind you, just lets say there are 'cleanup crews' out there for things like this... 3rd party companies with plenty of experence with this kind of thing....
a bit of trivia; the biggest leakers of personal data? hospitals... (no im not kidding)
