You might have seen some laptops have screens that fold down, I know MacBooks do. This "clam shell" effect protects the keyboard, trackpad, and even the screen from bumps and jostles. Many laptops when so closed can even fit in a backpack.
So a little trick I figured out is to close my laptop lid and then slide it into a pocket of my backpack. I can then carry it with me when I get up and move around.
So then I can take it with me to eat lunch or an extended toilet break. Maybe some day all laptops will have that feature.
