The only ones I've seen with individual holes are the all soft type cases. That one has an acrylic back and so far I haven't seen one with anything except the P cutout or a rectangle cutout.
I think the holes would be cooler but like you I got one with the acrylic back and soft sides. I was thinking of picking up the lens covers I've been seeing. Individual disks that cover the cameras. They wouldn't change the look of the device but they'd offer a little more protection.
