People would buy beautiful laptops, with glossy finishes, interesting detail. Yet, people would never pull the original plastic off the surrounding covers or back cover. They would bring in their computers to be worked on and have this hideous, dirt crusted, half pulled up, sheet of plastic flapping in the breeze on their computer. I would ask them why they did this and they always said the same thing: "Because I don't want to scratch the laptop."
I would then go through my speal about how, if their entire purpose for keeping the plastic on was to keep it looking pristine, why did they put up with it looking like shit for years. By the time they get sick of dealing with said plastic, they will pull it off only to realize that the dirt and grime that has accumulated under that plastic causes tiny scratches in the surface of their laptop.
In summary: Laptops with plastic on them looked like shit to begin with, once removed the laptop still looked like shit from leaving the original plastic on. Take the plastic off, enjoy how beautiful your laptop is and try to take care of it to the best of your ability. Nothing lasts forever.
