My friends on the other hand are VERY Careless about this. They do not care pretty much and give me their laptops to repair with their credit cards #, SSs, etc.

Of course I don't look at that info, but I don't think they know I have access to this. Also, they never leave me the passwords to update the computer, so I either hack it (usually their name or just empty) or reset it in the Mac OSX Disk.

So yeah, night and day.
