Continued shape of my main task magazine

I have been thinking about the shape of my magazine and I have decided that one of the shapes that I could produce is the "ipod" shape. It is a well regonised shape throughout all ages and has potential to strike my market audience and portray a new look on magazines. If I am going to produce this shape I feel that I should keep it to the real life size of an ipod or round about that size. Although, this may cause it to be lost in the shelves of other well known magazines.
