To all you MBP and Powerbook users. Do your laptops scratch easliy? Does the paint wear easily? I finally got my MBP and I want to make sure it looks this pretty for as long as possible. I considered getting this product http://www.shieldzone.com/category/laptops/. I got one for my Ipod and its the most durrable coating i've ever seen. My question is "is it nesessary?". Its kinda expensive if I don't need it but I wouldn't mind paying the price if these things are delicate. Thanks guys!
