New MacBook Air Retina Display

The new MacBook has a 12-inch screen, which joins Apple's Retina display family with a 2304 x 1440 resolution. Apple says that it consumes 30 percent less power than previous displays. The touchpad has also been overhauled: it no longer clicks. There are four force sensors, one in each corner, and the "click feel" is managed by software. That allows the MacBook to have pressure sensitivity, which leads to cool new uses such as pressing harder on the fast-forward in QuickTime to make a video play faster. Apple calls this a Force Click. It weighs just 2 pounds and, at 12 inches, will sit in between Apple's lightest MacBook Air models. It's 24 percent thinner than the 11-inch MacBook Air, measuring 13.1mm in thickness. There's an all-new keyboard, which spans the full width of the new MacBook. The keyboard features a new "butterfly mechanism" for a better, "much more precise" typing experience. The keyboard also has individual LED lighting for each key, helping to make the device that little bit thinner.
