Apple (AAPL) famously introduced the world’s first Retina notebook a couple months back, but notably missing was it’s smaller 13-inch brother. Introduced yesterday at the company’s Fall event which also saw the introduction of the iPad mini, brand new iPad, iMac, and Mac mini, the 13-inch Retina MacBook Pro is already shipping to customers and available at some Apple retail locations. As much as I wanted to love the 15-inch version, coming from a 13-inch MacBook Air proved too difficult. The new 13-inch is a beautiful compromise, and only weighs half a pound more than the MacBook Air. The notebooks design is identical to the larger computer, so this makes two options for the best laptop Apple has ever made depending on your screen size preference. I don’t think it’s long before we see the MacBook Air simply turn into the MacBook, with the Retina MacBook Pro obviously just being MacBook Pro. Since I never reviewed the 15-inch laptop, I’m going to review the 13-inch, and I’m excited.
