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.
It is definitely not worth buying a 32 GB model or a model with Cellular data, which would push the price of the Mini equal to or above the iPad Mini 2. But even the low-end iPad Mini will only save you around $30-$50 off the price of a Mini 2, and the iPad Mini 2 is a much more powerful device. The iPad Mini was based on the iPad 2, which was Apple's second-generation iPad.
