anyone know any macbook protection film? ive seen some online such as appleez, bodyguards, invisible shield, etc. but i am not sure if they are good buys since i am worried that it might leave any residue when i take them off. i thought of buying a clear case, but there are alot of reviews that say that it scratches the macbook easily. which one should i get? since white macbooks get easily scratched due to its plastic design. any advice?
