They've got my request too. I stressed the fact that the N9 and the better known/sold Lumia have the same shape and size, except that the Lumia has an additional key on the side, which means that a housing for the Lumia would fit on the N9. That being said, I also stressed that the N9 is a Linux-based device with a well established community, with many people coming from the N900 and its hardware keyboard.
