I agree. Most people are just blowing this out of proportion. My iPad has been just fine. I couldn't be happier with it.
First of all, what exactly did consumers expect? Apple took essentially the same chassis as the last iPad (the iPad 2) and built in four powerful new components: the A5X CPU, a quad-core graphics processor (it’s on the A5X but still counts as GPU), a 4G LTE radio and the ultra-high-rez retina display. Guess what all of those generate? Heat! Apple increased the size of the iPad’s battery just to support all the extra juice these components would need. It’s a natural law of technology that more powerful components eat more energy and thereby generate more heat.
