I just might sell my MacBook over this. How many of us honestly look at the back of our laptops? Well I did tonight and what do I see- stress cracks around the hinges, around the vents, and all along the back edge! Just look at the pictures! I'm never rough with my MacBook. It lives inside a Louis Vuitton messenger bag with a suede interior, and if it's not there, it's on my bed! It doesn't get much more comfortable that that!
