First I'm sorry to hear about your wife's pain. Due to the poor quality of that picture, that does not look like a burn. Her leg appears patterned, and a warm mac book pro would produce a patch of erythema, as opposed to scattered small patches like in the picture. Nonetheless, regardless of the poor quality photo, it looks like a first degree superficial burn (equivalent to a sunburn) and she should make a full recovery.
First, there's no need to be abusive.
Agreed, but he wasn't, he was stating that the owners manual has warnings, much like a hot cup of McDonalds coffee, that there is significant enough heat production to produce a burn so had fair warning. By the statements made, sounds like she was putting a bare mac book pro on her bare skin... a poor idea for any notebook.
Second, regardless of what Apple's manual says, I
think that you would agree that being told that you
cannot use a portable machine in a portable fashion
is nonsense.
You can use it portably; its portability does not indicate that it should be used for a prolonged duration on a lap. Technically an iMac is pretty portable too, you just don't want to carry it around though.
Imagine for a second that you bought a
new car. You take it out for a spin on the freeway
driving at a normal speed, the engine siezes, and
your car is now--for all extents and purposes--dead,
and you were nearly killed in the process. You
complain to the manufacturer who is refusing to
repair the car, and they tell you that it's entirely
your fault for not reading the manual, which clearly
states that you were not supposed to drive your car
on the freeway. In fact, it's only rated for surface
streets and dirt roads. How angry would you be?
Actually it's much different... Your wife did not experience a near death experience, I don't sympathize nor appreciate your analogy. If you said that they had heated seats, and the manual says May cause buttock burning, I'd totally agree with you... and would make a completely appropriate analogy.
I know this is an exaggeration, but let's be honest
here: if you get a product that doesn't work in the
way that other similar products do, you're going to
be upset. I can go out right now and buy a Sony,
Dell, or Gateway notebook and use it on my lap
without injury. Why shouldn't I expect to be able to
do the same thing with comparable hardware from Apple?
No, all laptops get hot. All laptops have the potential to create a burn, it's the whole process of physics and distribution of energy.
I know I'm being a jerk, and I don't care. You were warned in the owners manual, and if your wife doesn't have the neurovascular capacity to sense an overwhelming amount of heat that my cause a burn, I suggest she gets checked for some peripheral neuropathy, because most people know to take something hot off themselves if it feels too warm.
And if she thought it felt cold, I suggest she goes to an emergency room immediately to rule out severe neurologic dysfunction.
Good luck with the repair, and be sure to wear some pants and use discretion when placing a warm laptop on your legs.
