I have been using a Dell Inspiron E1505. It has been working well, but I am hoping to get a new laptop. I have been hearing a lot of good things about the Macbook White. The only complaint I hear is about how the edges are especially sharp. Some of my colleagues have suggested that if I were to get a Macbook White, I should also invest in something called the Marware Protection Pack. Does that help with the problems about the sharp edges?
