So I bought a MacBook Air 11 inch on Saturday, and I want to know how I should protect it. I bought the Speck Hardshell case for it, but I'm not so sure about it. I am wanting to resell it next year, and my concern with the speck case is I've had a hardshell on two other MacBooks, and even though I cleaned out the case a lot, it damaged both of them over time because stuff still got inside and put little marks on the inside. Does the Speck hardshell protect against dents, especially because the 11 inch hardshell feels a lot thinner and more flimsy then the one I have for my 15 inch with retina display? If I were to use something else besides the speck, what do you recommend? I'm also thinking about getting the best skins ever, especially if the speck doesn't actually protect against dents, but I am still a little worried about dents.
