You have to respect entrepreneurs for jumping on trends. MacBook sleeves have materialized which are lined with graphite so that they are fire retardant. I’m not sure how this will help exactly, but with battery fires on everyone’s minds I’m sure they will sell a bunch of them. The covers, called Wrappers, which look like a blankie for your notebook, cost $30 each. They are cheap enough to let you buy peace of mind if you are worried about such things. They come in a full range of colors, so you can be stylish while letting that paranoia go.
