The newest member of the Apple iPad family, the iPad mini with Retina display was released today.

Starting today, shoppers can purchase the iPad mini with Retina display from Apple's online store. The new tablet, however, will not available in brick and mortar Apple stores. Shoppers who enter an Apple store hoping to get their hands on the newest iPad mini will have to place an order online first and request in-store pick-up. The tablet will also be available through AT&T, Sprint, T-Mobile, Verizon Wireless and other Apple Authorized Resellers, ABC News reports.

The new iPad Mini will feature the A7 chip, making Wi-Fi twice as fast, but not taking away from its 10-hour battery life. The A7 chip also makes the iPad eight times faster than the original iPad, with graphics performance that is 75 times faster.

The tablet's Retina display screen is 7.9-inches and has 2048 by 1,536 resolution.This enhanced resolution results in sharper photos, videos and text. iPad Mini with Retina display, an Apple-created term that means pixel density "so high the human eye cannot distinguish individual pixels from a normal viewing distance, so text and graphics look incredibly sharp," will cost $399.

The iPad is in short supply, however. Because of its complex screen, dead pixels and other malfunctions result in a 50 percent success rate during manufacturing. This means that if one million iPads are produced, at least 500,000 will be trashed.

"Yield rates vary but reportedly range from 50 percent to as high as 70 percent," Rhoda Alexander, IHS iSuppli analyst, told NBC News.

The new iPad mini without Retina display will cost $299, a drop from its predecessor, which cost $329.

Meanwhile, shoppers will have to decide between these two mini tablets and its sibling, the iPad Air. The iPad Air is 43 percent smaller than its predecessor. The tablet is 7.5 millimeters thick, 20 percent thinner than earlier models, and weighs one pound, 0.4 pounds less than the iPad 4. The iPad Air keeps the 9.7-inch screen of its predecessor by removing some of the bezel that surrounds it, and, like the iPad mini, features the speedy an A7 chip. The tablet starts at $499.
