Gaa!
Its "Fan-boyz" vs. The class-action reactionaites in a death match where everybody loses!
As a long time Apple guy (Apple I on), I did a road trip and used it for hours in the car... It got pretty hot, but only on one end of it, but it was enough that I commented to my wife about it. Not the end of the world, but not insignificant either. Its nothing compared to my iPhone 4 though, that when running GPS in the car got so hot that the sticker I had on the back of it melted off (adhesive melted) and I shut off the phone for fear it was going to burst into flames. End of the world? no, but I wish they didn't get so hot.... Here's a test to try. Get in a warm car, play infinity blade II while you have the GPS with online (4g) services running.... I bet you could make toast on it! - Cool toy though. Love the screen, but I was most impressed with the camera. In good light it takes nice snapshots....
PS, It was an ok, but not earth shattering upgrade from the iPad1 (which I kept also). I wouldn't bother if you have a ipad2. In fact, a used iPad1 is probably the best deal right now, and the cheaper price on the 2 makes that a good deal... Seems best to skip a generation or 2 on Apple stuff.... For that reason, I didn't get a 4s phone, but will wait for the 5....
