The biggest selling feature of the next generation MacBook Pro is its Retina display. The notebook has an impressive 15.4-inch LED-backlit display with 2880-by-1800 resolution at 220 pixels per inch.
The specs look great on paper and according to a display-focused review by The Verge, the display looks amazing in person, too. This improvement is best seen in a side-by-side shot of Chrome on the non-Retina MacBook Pro and a Retina MacBook Pro. Text, which has blurry edges on the MacBook Pro, is crisp and defined on the Retina MacBook Pro. As noted, the Chrome team is already working on a Retina update; you can see the effect already if you want to run the Chrome Canary bleeding-edge nightly builds.
