The new iPad runs a little warmer than previous generation models. This has caused some concern for users who are saying that their own iPads are getting far too hot. Apple was contacted about this and has responded with the following:

“The new iPad delivers a stunning Retina display, A5X chip, support for 4G LTE plus 10 hours of battery life, all while operating well within our thermal specifications. If customers have any concerns they should contact AppleCare.”

I personally have seen a difference between the temperatures of the older and new iPad models although it certainly doesn't get "hot"... it just warms up a little and seems to happen after using it for a couple of hours.

Tweakers.net has used a thermal camera to see exactly what the temperature difference was on their test unit. Under average use it runs 4.3 degrees C warmer.
