I'm not sure anybody's saying that there's a widespread overheating issue. The other poster just asked about it, and I pointed out that there are several reports online.One question emerges based on the reports.
What were the circumstances when the overheating in the direct sun occurred?
Apple specs indicated 95 degrees.
Without knowing more, how can anyone conclude that there is a widespread significant issue over any other device in the sun
The circumstances of the reports don't seem to be anything particularly extreme.
