If you're hooked on Apple's Smart Cover design and you've wished you could somehow mimic its propping functionality on your laptop, AViiQ's Portable Quick Stand might work for you.
Like the Smart Cover, the stand goes from flat to a 3D Toblerone shape, supporting laptops like yours (or others', up to 17 inches in size). At 3.4 oz and measuring 3/8 of an inch thick in its folded up state, it's perfect for a quick stuffing into your bag when you're headed out the door. Also, its makers claim that the stand reduces wrist strain and increases air flow to improve your laptop's battery life.
It's $40 from AViiQ, and comes in a variety of colors. [AViiQ]
