I'm picking up a 13 inch Macbook Pro for college next week and I'll need some sort of bag/sleeve to carry the laptop in. Any suggestions for some good,(preferably) cheap options? Also, I'd like to look into some sort of "Shell" to cover the Macbook to prevent scratches and such. I've heard mixed reviews about the "See-Thru" hard shells, so I was wondering if any of you had any experience with them or another similar product that may be better. Thanks.
