So right now it's 78 degrees out, sunny, and that is great news. Thing is, where I am sitting inside, has air conditioning, and that is great news. Problem is I sit in a place where the AC apparently like to go bizerk and turn this room into antartica. Can't turn it down, because everyone else's office is perfect, and only my desk is like this. It's cold, like really cold in here, probably 63 but with cool AC blowing all the time and you are just sitting here. I actually have goose bumps and even shivered a couple times. (I am dressed like it's 78 out) So.... with no other option, i decided to make my MacBook Pro a heater. Step 1. Fire up Steam Step 2. Launch any game, in my case CSS Step 3. Feel the roast, and heat wafts off your notebook, warming your hands and arms. My notebooks still runs very very fast with the game minimized, but still pumps out the heat. Great!
