I'm debating between the VYPER XS3 and the Incase Perforated Hardshell Case/Regular Hardshell Case. I'm going to be a second year college student in the business school and will be carrying around my laptop often either in my backpack or in my own hands. I'm also debating on which keyboard cover to get between the Moshi and Iskin. Both seemed overpriced and I have limited knowledge on macbook accessories. Advice is appreciated.
