Qur'an Perfectly Preserved?

For a long, long time, Muslims have been told that the Qur'an has been perfectly preserved in Arabic, down to the last letter, but Muslim scholars themselves are now admitting that there are differences among the various Qur'ans throughout the world, not just in the vowels used, but also in the consonants, and even in the wording, and this has made some of the Muslim faithful angry over having been lied to about the Qur'an's perfection, and some of the faithful are even reported to have left the faith over this issue, which I suppose renders them "the faithless" now.

I'll be interested to see what becomes of this issue as more Muslims learn of it.
