Actually, the iPad does overheat quite rapidly if the screen is nearly perpendicular to the Sun's rays. I take long walks almost everyday with the iPad as I stop and have lunch and do a little reading while I eat. I also will open the iPad and do some reading as I walk. I have learned to tilt the iPad away from the Sun's rays so it won't overheat. If the rays hit at a glancing angle, there is no problem. I think a law suit over this is ridiculous because the iPad is not permanently damaged (the heat sensing shut-down works well), but people will sue just for the hell of it to see if money will rain from the heavens.

The quickness of the overheating is surprising, just a few minutes. I think the glass and conductive touch sensor coating let the infra-red in, but not out. Very efficient, but inadvertent passive heat absorber as the iPod feels quite hot. I don't think the iPad overheats itself by cranking up the power usage - the LED screen doesn't get any brighter when facing the Sun. In fact, the auto-brightness doesn't work yet.
