Yesterday’a revamping of Apple’s MacBook product line resulted in a product portfolio curiosity. Apple’s notebook lineup now varies about as much by girth as it does by screen size. MacBooks remain available in three screen sizes but the 13″ model is also available in three thicknesses — the ultrathin MacBook Air, the slim MacBook Pro with Retina Display, and the classic MacBook Pro with SuperDrive (unbranded as such). Of course, there are other differences among these models such as storage options, ports and screen resolutions. Still, the MacBook line now can be thought of as having three sub-lines: Air, Pro and Pro with Retina Display.
Making them even more like product lines, they tend to have similarities across the screen sizes. While the Air and Retina lines both lack optical drives, the former is obviously engineered for the ultimate in portability and a cloud-friendly lifestyle while the latter is for the leading-edge power user, with the non-Retina Pros playing very much in the mainstream. As Phil Schiller noted, the 13″ MacBook Pro is Apple’s best-selling notebook and seems likely to remain so after its Retina-equipped sibling.
