My one concern is that nano-texture apple displays are a little more sensitive to damage, and even being super careful with my MBPs I get the little marks from the keyboard when you carry the laptop with your hand squeezing the lid and bottom (a natural carry motion).
A piece of paper also kind of works, but it's a bit ridiculous to constantly keep that around with you and try to reach 95% consistency. Eventually I stopped trying because it was just more infrastructure to protect the thing than I'd prefer.
