I saw a bumper sticker the other day that said, "If it ain't King James 1611, it ain't Bible." Although I consider the King James / Authorized Version of the Bible to be a masterpiece of English literature, I'm curious why all other versions- perhaps including translations into other languages or even original-language versions or ancient translations like the Septuagint- might be excluded.

What translation of the Bible do you use? If you're a KJV-only person, why?
