Apple Predicted to Release Ultra-Slim 12-Inch MacBook with Retina Display in Mid-2014
Specifically, the new MacBook is expected to feature a clamshell form factor even thinner than the current MacBook Air, and may debut at a lower-price point than the current Retina MacBook Pro line due to an improving yield rate. While Kuo stops short of calling the new model a replacement for the current MacBook Air line, his description of the model suggests that it would indeed supplant Apple's current ultra-slim notebook line.
We expect the unprecedented 12” model will boast both the portability of the 11” model, and productivity of the 13” model. The high resolution display will also offer the outstanding visual experience of the Retina MacBook Pro. The offering will likely be lighter and slimmer than the existing MacBook Air to further highlight ease of portability in the cloud computing era. We think the form factor will showcase a much improved clamshell structure, and that it will redefine laptop computing once again following the milestone created by the MacBook Air.Kuo's claims match with a report from NPD DisplaySearch analysts earlier this week claiming that Apple is planning to introduce a new 12-inch MacBook Air next year. That new model was predicted to use a high-resolution 2304 x 1440 display
Both rumors also fall in line with earlier reports that Apple is set to move to IGZO displays for many of its future products, allowing for higher-resolution displays with lower power consumption.
Kuo has generally been quite accurate with his predictions over the past several years, including accurately outlining many of the details of Apple's 2013 launch plans as far back as January. Other accurate predictions have included the introduction of a "third MacBook line" that arrived in the form of Retina MacBook Pro models and the discontinuation of the 17-inch MacBook Pro last year.
