In the recently released series of tablets iPad 4 and Kindle Fire HD 8.9 have similar configuration. They both have 4G LTE feature.
Kindle Fire has a 1.3 megapixels front camera for video calling. And it lacks the rear camera. But the iPad has a 1.3 megapixel front camera and a 4.5 megapixel rear camera is far better to take picture and record video. Thus the iPad 4 is far better in camera’s angle.
