So I read the iFix it teardown article but did not find my answer. I have the Apple keyboard and do like the light touch...don't need the added features of the Logitech Create, though it was tempting. Because the Apple keyboard does not have a back cover, wanting to protect my Pro, I decided to apply my own cover, or combining Zagg alligator leather back that was made for an earlier iPad. I still had two that I used to cover the keyboard/cases. So I've matched it up, trimmed to fit. It looks good even with the seam down the middle. The design matches placed side by side, trimming the edges to keep it even... My question: What is the black strip for beside where the camera lens is on the back? Can I cover it with the Zagg leather skin, or should I use a cutout to leave it free from interference? I don't see the cover/cases leaving it free. Just wondering why the strip.
