iPad Air 2 it is the fifth tablet iPad with 9.7 inch screen and the 7th in the complete line of Apple tablets released over the years, and in the table below we have the opportunity to see it compared to its "sisters". As you can already see, in three years the size of the screen and its resolution have remained unchanged for iPad tablets, the only differences existing in terms of design being their total dimensions and thickness.
The hardware has evolved from year to year, except for the main camera, which had an upgrade this year, with Apple at the same time improving compatibility with LTE frequencies, or Wi-Fi connectivity. All in all, iPad tablets have evolved significantly in recent years, but not extraordinarily much, as some would have expected.
