What exactly does Retina mean on a computer where resolution is tied to how much you see on screen (spreadsheet cells, words per page in a document or web page)? Mac OS X now increases pixel density for the Retina, so you're getting 220 ppi rather than the usual 110ppi.

Retina Display: Emperor's New Clothes or Worth Buying? But the biggest change is the Retina Display, a term we're familiar with on the iPhone 4S and new iPad. Still, it's as close as we'll get to a 15" MacBook Air at the moment, and the MacBook Pro with Retina display is more than twice as fast, placing it squarely in the Pro class among MacBooks. At 0.71", it's nearly as thin as the 13" MacBook Air at its thickest point, but it lacks the Air's recently patented taper, and it's not nearly as light as the 3 pound Air. The unibody casing introduced in 2008 is alive and well, but the Retina is 25% thinner than the MacBook Pro 15", and 1.1 pounds lighter at 4.46 pounds. It's put together as perfectly as you'd expect from an Apple product and it looks stunning in a quiet and tasteful way. This is Apple's next generation MacBook Pro and it brings a slimmed down design, lighter weight and new ports: HDMI and two USB 3.0 ports. The MacBook Pro with Retina Display has only been out a few days, yet it hardly needs an introduction. 2012: Also read our review of the 13" MacBook Pro with Retina Display. What's not: Expensive, parts not upgradable. What's hot: Slim, light, fast and that Retina display!
