Sorry if this has already been said but I have some insight as to how hot surfaces can become even in "moderate" ambient temperatures. Detailing cars and working on roof's has taught me even a mild day can produce some burning surface temperatures.
I used to be quite obsessive about keeping my car's clean. Particularly my black Mustang. Loved that car. But if you know anything about waxing cars you should know not to do it in the sun, because the car's surface gets too hot and the wax dries up quickly, making it near impossible to wipe off.
On a 75 degree day in direct sunlight the surface of my black car reached 120 degrees F. This is after only 20 minutes of sun, and I know this cause I'm crazy. I timed it and used a temp gun.
I'm speculating but I imagine the surface of that black bezelled glass Ipad would get nice and toasty. On an 85 degree day I can definitely see the surface of the Ipad reaching 113 degrees in direct sun. In the shade? Its a crap shoot. Lots of variables there. Reflective light or a breeze can change those numbers significantly. So even if its a "moderately" warm day I would urge caution to my fellow Ipad owners.
Sorry to hear about the OP's problems. Definitely sounds like your first Ipad was defective. Don't underestimate the power of the sun.
