<p>A trick I use to protect my screen is to put a cleaning cloth - like the one they give you with it - inside when I close the case. I make sure the cloth isn’t lying on the fan vents, which are usually near the hinge. When a case is compressed, the keys can leave slight marks. The marks are mostly bits of grease from your fingers that have transferred and can be wiped off but the cloth helps and then it’s there to use.</p>
<p>I’ve never bothered with a screen protector but I know people who like them.</p>
