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.
The iPad Mini 2. Don't mistake the iPad Mini 2 for a budget tablet just because of the $269 price tag. The Mini 2 is modeled after the iPad Air, and while it isn't quite as powerful as an Air (the processor is the same as in the iPhone 6), it is still a snappy tablet.
