Quran is a book I agree but then we respect that book and we cannot treat it that way. We are not even supposed to touch it when we are not clean and pure. But on the other hand, the same Quran is on the Ipod or on the computer, laptop, mobile, etc it is not the same thing. If someone downloads a soft version of the Quran on a PC and then burns the PC then it would not have the same effect but burning a written Quran in the form of a book means a lot to us..
