I'm very surprised of how the device cools itself.. so thin, so small and i never notice any warm coming from the device. I've played extensive 3D games for hours and never notice anything! I love it!
You poor person! Though I am doing something similar to my partner for her mini, but she has a iPad 2 in the mean time, which will be returned to Apple before Christmas in exchange for Apple vouchers!
It was the ipad 3 and now 4'th gen that bumped up the heat, but yeah the Mini even after a session of Modern Combat 3 is a pleasantly cool little number
