Look guys, at the end of the day, you have to decide what you're comfortable with. All I know is that not a day goes by where I or one of my colleagues don't have to fix a problem caused by some piece of software that one of our 400 + users downloaded from the net and installed on their computers.
Anyway, I think we've exhausted this topic. Let's get back to the one thing we can all agree on and that's our love for these cars, ok?
