Flip down latop feet
We all know heat is a killer for laptops, many people opt for a cooling pad or riser to help vent out some of that heat.
So, why not just have something like a riser built in. Using the flip down feet like a keyboard has (2 heights to choose from) would allow users to prop up the back of the computer for better air flow, then flip the feet back in to put the laptop into your bag.
There is a company that makes stick on ones that do this, but they are large and ugly.
