Along the same lines, my new (to me) Apple Thunderbolt display generates a ridiculous amount of heat, and the vents are on the bottom, right above my keyboard (I have the display on a VESA mount). Which is great, because my hands get cold easily and my office doesn't get very warm. It won't be very fun come summer though.

This idea might not have changed my life, but it changed my day :-) (Within seconds and for the better; what more could you ask for?)
