Competing with the 11-inch MacBook Air, the UX21 will have an 11.6-inch (1366 x 768) display, weigh a netbook-like 2.2 pounds, and is 0.7 inches at its thickest point. The chiclet keyboard will be made out of an aluminum alloy, just like the rest of the notebook, and it will feature a glass trackpad. The UX21 includes two USB 3.0 inputs, a headphone port, and a mini-HDMI out connector. Inside the ASUS UX21 is said to have a Core i3, i5, or i7 CPU along with 4GB of RAM and a 64GB or 128GB SATA 6Gb/s SSD. The spun metal finish really separates this Ultrabook from the rest of the pack.
