For me, that just defeats the purpose of the Macbook. It delegates all of its aesthetics. People think that they are personalizing their laptops. They think that by adding these silly stickers or buying these colorful case protectors that their being unique in some way. News flash: It's not. It just devalues your Macbook. The Macbook's look is known for it's simplicity. It's only in the finer details that separate the Macbook from it's competition.
