whatz the exact difference between the glossy display and the ratina display??

Billions of colors according to Apple. http://www.apple.com/macbook-pro/features/

Oops I means half billion (5.1 million pixels)

The regular glossy display has a lower pixel count than that of the retina display. The retinal display has more pixels than an HDTV so that means sharper text and clear pictures. Plus it is loads more expensive! 😀

Hope this helps.

ooooh. That sounds right. The glossy if the default display on the macs but any of the existing diaplays are lesser quality compared to the retina diaplay.
