Hi, I have a macbook and I take great care of it. Since I love not only working with him on the couch, but also eating, I bought a great keyboard case that fits the new Macbook Air. It perfectly prevents dust and dirt from getting under the keys. Of course, the addition of a silicone layer makes the keys softer and harder to type on, but I find a laptop keyboard case an obvious trade-off for using a keyboard case. Using such a cover will extend the life of the keyboard.
