How it should be in your opinion is not how it is done.

Ambient temperature should also be taken into account. Not really concerned with the longevity of the device. I know that electronics tend to have higher thresholds than humans do. No idea how Apple came up with their thermal specs so can't really make a comment on their statement.

You already did. Ambient temperature is taken into considerations and it defined as the operating temperature of the device.

No idea what the human threshold of pain is when it comes to heat so don't really know if 114F is bad or not. I do know 80C is hot enough to cause blisters (accidentally touched the heatsink on the Atom when I was doing some maintenance).

Sorry I didn't convert it for you. that would be 45C.

Even if there's nothing that can be compared with the iPad right now in terms of resolution, it doesn't mean that other tablets don't get as hot particularly those with quad-core processors, etc. The iPad is a high profile device and I reckon it does log a lot of hours use with the CPU and GPU stressed. That's the reason it's getting all this coverage. However, just because it has the highest resolution doesn't mean it also runs hottest. Design matters a lot. Granted, Apple relying solely on radiation for heat transfer may not be the best of design choices.

Other tablets can certainly get hot for many different reasons that are unrelated to the discussion. the Apple seems to being getting hot due to the increased needs of the high resolution display. It takes 4GPUs to offer exactly the same performance as one GPU on the current iPad 2. The screen has 4 times the number of pixels and requires 4 times the horsepower to achieve the same results.
