All,
I just read what I posted, and it sounds harsh. I did not intend that at
all, and I wanted to apologize to Bob publicly if I offended him in any way.
He did a GREAT job detailing the differences and I just wanted to add a
few refinements. I did not want to sound as snotty as I did in that post.
