You can now pre-order the Apple iPad Air 2 and Apple iPad Mini 3 online from the Apple Store
Perhaps a 7.9 inch screen is more to your liking. The Apple iPad mini 3 can be pre-ordered in the same three colors as the iPad Air 2. The Wi-Fi only version of the slate can be pre-ordered with 16GB ($399), 64GB ($499) and 128GB ($599). If you want 4G LTE connectivity, the prices are $529, $629 and $729, respectively.
Both new iPad models will start shipping next week. If you want to pre-order either tablet, you might not want to dilly dally just in case Apple sells out of the new slates.
