I’m quite careful with these glossy plastic displays after managing to really scratch up the one on my Peak when trying to clean some smudges with a microfiber cloth. Also got a tiny one (not really visible unless you look at it under a light) on my Hydrasynth, where I was extra careful that the cloth was clean etc. Seems they can be quite succeptable to scratches!
That said, I can’t be bothered being too precious as all my gear ends up with some kind of injury at some point managed to drop my A4 on my Macbook last night luckily just a couple of harmless dents in the top!
