What is the best way to prevent keyboard marks?
If you're not careful, over time keyboard rub marks (particularly on the center row) can render a display almost unusable. This issue was particularly pronounced for me when I carry my MacBook Pro around with me in a backpack with lots of equipment.
I've used a piece of paper in between the keyboard and screen, and that gets the job done but isn't terribly elegant. What works best for you?
Is this a good question?
