The MacBook Air 8,1 (13-inch, Late 2018) has the following advantages: Retina display with thinner bezels, more powerful Intel Core i5, faster operating memory LPDDR3 2133 MHz, better Intel UHD Graphics 617, greater SSD storage (128GB and 512GB), two Thunderbolt 3 (Type-C) ports with up to 10Gb/s data transfer rate, HD FaceTime 720p camera, touch ID fingerprint scanner, the “butterfly” keyboard of the 3rd generation, the price starting $799 for minimal configuration. Actually, this is the cheapest Retina-featured product by Apple. Also, this is the first Mac with the Touch ID. The biometric authentication for laptops was introduced by Microsoft for the top Windows laptops several years ago, but this feature failed to appeal to the public. Probably, because simply installing the fingerprint scanner into the keyboard is not enough. Apple did a great job implementing the Touch ID into the iOS-macOS ecosystem. Now it works as a login tool not only for the device but for the passworded apps as well as for Apple Pay. Left-handers, unfortunately, will have some troubles using the scanner as it lives in the right upper corner. New never used
