Stickers on the laptop was such a small, wonderful part of college for me. Very minor, but the strategically perfectly imperfect placement of a sticker on my laptop when it was deemed to be worthy was so much fun. My favorite was a sticker meant for a hot beverage carafe to label it with the contents that I took that just read "HOT WATER".
I have a Framework now and haven't adding anything to it (because it's easier to clean), but maybe I'm missing out.
