What I found really funny is that CR did not even mention warmth or battery power in their list of "lows". Their lows were lack of memory card slot (which can be remedied with the Camera Kit) and the lack of Flash video compatibility, which has been an issue with all iOS devices.
Their final conclusion on the heat is: "In response to consumer comments on the new device, we carried out tests that demonstrated the new iPad is warmer in its hottest spots than the iPad 2 under the same test conditions. However we didn't find those temperatures to be cause for concern."
As for the battery not charging while playing Infinity Blade II, they have now done more tests:
"In further tests, we continued to find that the iPad would slowly lose charge with that game, even with the charger connected. But when running another challenging game, Shadowgun, which is available for both iPad and Android, the tendency was less pronounced; the battery did not run down but slowly recharged as the game ran.
Sounds like the main issue may be Infinity Blade II. Maybe they should take it off the Apple Market and end the complaints?
"Our findings suggest that if you're a serious gamer, you might want to manage how you use the new iPad by reducing screen brightness when possible, which will not only reduce heat but increase battery life and facilitate full recharging. Other consumers should find little of concern in our extended tests, on either the heat or recharging issues."
