The Fluid Filled Cochlea. The pressure changes in the cochlea caused by sound entering the ear travel down the fluid filled tympanic and vestibular canals which are filled with a fluid called perilymph.
Those who love the size of the original iPad Mini 1 will be pleased to find that the size remains unchanged. Both the iPad Mini 1 and the iPad Mini 2 both measure in with a height of 7.87 inches and a width of 5.3 inches. The iPad Mini has only a slight difference in depth, while it weighs slightly more. However, it is still lightweight enough for anyone who wants a small and portable tablet.
This is both a big advantage and a big disadvantage for the iPad mini. The good news for Apple's tablet is that it gives you much more real estate. The Fire HDX only gives you 74 percent as much screen area. Notice that the iPad mini's screen also takes up a much higher portion of its front face.
