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.
All those shiny features come at a price. The iPad Mini 4 starts at $399, Â£319, AU$569 for the 16GB Wi-Fi model, $499, Â£399, AU$699 for the 64GB version, and $599, Â£479, AU$829, for 128GB. But the larger iPad Air 2 -- which is quite a bit faster -- costs exactly the same, making it a far better deal.
