Would you call us crazy if we told you that the display assembly from the latest MacBook Pro is the same size as its predecessor?

You caught us; we lied. The new display is actually a fraction of a millimeter smaller than the old one. Neat!

At its fattest point, the display assembly is a hair over 7 mm thick, and all the way down to just over 3 mm at the edges.

What's astounding is that Apple's engineers managed to cram four times the pixels of the previous 15" MacBook Pro into a display assembly that is (nearly) the same size.

The big savings here is weight, not thickness. The Retina display weighs in at 673 grams, while a standard 15" MacBook Pro display tips the scale at 908 grams. That's a solid 25% weight savings!
