Ok, that's fine.
The Qur'an in its literal form means recite/recitation, when its read. The written text is Kitaab literally means Book.
As the Quran was being revealed, Prophet Muhammed (saw) made special arrangements to ensure that it was written down. Although the Prophet Muhammad himself could neither read nor write, he dictated the verses orally and instructed scribes to mark down the revelation on whatever materials were available: tree branches, stones, leather, and bones. The scribes would then read their writing back to the Prophet, who would check it for mistakes. With each new verse that was revealed, the Prophet Muhammad also dictated its placement within the growing body of text.
When the Prophet Muhammed (saw) died, the Quran has been fully written down. It was not in book form, however. It was recorded on different parchments and materials, held in the possession of the Companions of the Prophet.
No doubt I'll be accused of avoiding the question and being argumentative, but I started to write an answer that was becoming an essay, and my memory meant I was leaning on google sites that I couldn't be sure of the credibility of, so I'll limit it to some broad points that can perhaps keep it reasoned, as I'm finding this interesting.
To clarify, are you maintaining that there's no dispute even amongst muslim scholars as to:
the number and content of the various codex?
The direct word of god, wasn't always a word, but could be a bell ringing?
That some companions tasked with remembering and reciting the text died in battle? That some texts were eaten by goats or torn up?
That there are conflicting narratives stating it was and wasn't written before his death?
In collating his hadith, al bakr (sp?) didn't whittle down over half a million narratives to a few thousand?
That the koran doesn't contain contradictions and abrogations? Purely as an example, what does the koran say man was made from? blood (96:2) clay (15:26) nothing. (52:35) sperm (16:4)
