Jacksonian, the "orange peel" is a common problem that is caused to stoneshield/invisishield when the rolls are left unused or too long. This is caused by the original manufacturer taking to long to ship material out after it is finished, or the end company(ZAGG/others) take tonlong to die-cut your material. Either way, it is a faulty material, one of which most people don't know about and automatically write on forums that it is bad as a screen material. It like a guy buying a car for the first time ever, having a wobbly tire, and questioning why or how people drive their cars with wobbly tires.
I am still waiting for mine to come in. I've been using the backing wrapper the came with te iPhone, even though it ruins night shots that require flash.
