Err, a) you clearly cared enough to respond this far, and b) the question is how do you know that you have not made a mistake not do you care if someone else thinks you've made a mistake
> how do you know that you have not made a mistake
I guess I just don't understand the purpose of asking this.
Because my operating system choice hasn't let me down or hindered me in any significant way?
I gave the "I don't care" response because I don't know how else to answer your question. "a mistake" is so nebulously defined that in this context it has nearly no meaning to me. Can you give an example of what you mean when you say "a mistake"?
