I have had my Macbook since March( 5 months, maybe less). I take it with me to work about once a week, always in a padded case inside another sturdy leather bag. I have never dropped it, and I am always careful with it. Today I noticed a 5 1/2 inch hairline crack along the front edge, origionating on the left side of the computer. The left side is also a tiny bit seperated and not the same as the right. I looked more closely and also found a two inch crack next to the CD insertion hole, and two -centimeter long cracks on the left side of the computer also! I pointed this out to my daughter who got her laptop in December ( 8 mos ago). She also has a crack on the front edge of her computer, and she never takes hers out of the house. I can't really work without my computer, but I definately don't want to see bits of my computer start breaking off, like I've seen in some of the photos. I hope Mac does right by it's customers and starts recognizing this problem and fixing it promptly.
