My iPad would over heat sometimes but not often. Judging by the "low temp" that seems to indicated an "over temp" warning...I assume it's just that, a warning and you are more than likely not doing damage to the iPad when it says that. It's a built in safety. However, keep it out of the sunlight, and you should be fine, crack the windows on a really hot day.
I'm buying another for my crews to use with SAP. I was just going to get the an iPhone, but if you add up the service cost, it's cheaper to get an iPad with limited Internet.
