Laptop stands come in all shapes and sizes. They need to accomplish two things, keep your laptop at a comfortable operating angle, and keep it cool. So long as they do both, the smaller the stand, the better. If you’re looking for the smallest possible, then look no further than the Portable Quick Stand from AViiQ.
You really aren’t going to find a stand that’s much smaller than this. It weighs a mere 3.4 oz and takes up no more than 3/8 of an inch when folded up. Yet its triangular shape props up your notebook to a comfortable angle on a desk, and its single point of contact leaves plenty of room for airflow underneath. If you don’t have a lot of room in your laptop bag for a stand, you might consider dropping $40 on one of these.

Might also try picking up two doorknob striker pads (from hardware store, or hardware aisle at local Target/Wal*Mart, etc). Got mine for less than $5. Take up VERY little space in my computer bag.
Hmmm, nice idea. :)
