Now that Apple has surprise everyone with the (not all unexpected) retina MacBook Pro, it seems clear that the MacBook Pro line which was launched in late 2008 will be replaced sooner or later. The non-retina 15" MacBook Pro will be completely replaced by the brand-new retina 15" MacBook Pro as soon as prices for high-resolution displays and for SSD drives allow it. There are also rumors that Apple will lauch a 13" retina MacBook Pro, and there are reports that those products will be released before October: http://www.macrumors.com/2012/07/10/13-inch-retina-macbook-pro-shows-up-in-benchmarks/ http://www.macrumors.com/2012/07/10/apples-13-inch-retina-macbook-pro-to-launch-before-october/ Although I don't really believe those rumors, it seems obvious to me that Apple will eventually put a retina display on its 13" laptops. But, if Apple redesigns the 13" MacBook Pro to follow the same path as the 15" MacBook Pro, it will have the following product: a 13" laptop weighing 3.6 lbs (considering that it would weigh 20% less than the current model, just like the 15" retina MacBook Pro weighs 20% less than the non-retina 15" MacBook Pro), equipped with a standard-voltage dual-core Intel processor, an SSD drive, an IPS screen with a 2560x1600 resolution, non-upgradable parts, and with no Ethernet or an optical disk drive. It's too similar to the current, similarly priced, 13" MacBook Air, which has 2.96 lbs, is equipped with a low-voltage dual-core Intel processor, an SSD drive, a 1440x900 TN screen, non upgradable parts and no Ethernet or an optical disk drive. The differences are just a few: the MacBook Air would be slightly lighter (0.6 lbs difference), would have a low-voltage processor (instead of a standard-voltage) and no retina display (but all Apple models will sooner or later get one anyway). Aren't they too similar? Does it make sense for Apple to have both? IMHO, Apple will drop the 13" MacBook Pro in favor of a beefed-up 13" MacBook Air with a retina display. Before 2009, Apple did not have a 13" MacBook Pro, and it may well drop it in favor of the Air. Any thoughts on this?
