I ran into my first temperature warning today. My iPad sat on the backseat of my parked car for 4 hours this morning. The iPad was in a leather case and the car was parked in direct sunlight. When I took it out of the car half of the ipad was in diect sunlight. I fully expected to get the temperature warning. In fact I was quite excited to see it. When I pressed the sleep/wake button I was greeted with this: I did not have my IR thermometer with me so I wasn't able to take a reading. The iPad was certainly hot to touch but not too hot that you could not hold the bare aluminum. 5 minutes in my air conditioned office was enough for it to become useable again Apparently the ipad does not shut down when in this mode. I was able to take a screen capture while the warning was on and when the unit had cooled down it woke up from sleep rather than restarted from the apple logo. There have been reports of iPads overheating even in moderate conditions, in some cases requiring an hour to cool down. My experience today was quite reasonable compared to those complaining to Apple. Anyone else get the warning?

Some iPads Can’t Take the Heat If you want to use your iPad in the sun, you might have to rethink that. Apple lists operating temperatures of the iPad at 32° to 95° F (0° to 35° C), which could easily be exceeded if exposed to sunlight for a length of time. http://bits.blogs.nytimes.com/2010/06/01/some-ipads-cant-take-the-heat/
This thread reminded me of those poor iPhones with wifi issues being put directly inside the fridge to cool down it's wifi radio. Hoping our iPads won't suffer the same consequences with those iPhones..but who knows...
