I'm looking to get some accessories to protect my device from damage or grime. So I was wondering if there are any recommended accessories for protecting the unibody and the keyboard? The speck case seems to be the most popular but I've heard that without regular maintenance it can actually scratch the Macbook. If that's the case it may not be worth it for me. As for keyboard covers, hopefully something that can come off easy if necessary and doesn't leave gooey residue. I have also read on Amazon that keyboard covers will if you don't protect the screen somehow they will damage it. Don't know if that's true. So I guess basically something that would be low maintenance and doesn't scuff up, scratch or make the Macbook sticky. Thanks!
