The new MacBook is less than half the thickness of its 2009 ancestor, measuring 0.52 inches at its thickest point.

At 1.08" thick, the 5 pounds of polycarbonate-swathed 2009 MacBook dwarfs our 2.03 pound Retina MacBook.

Apple probably shaved off a lot of that weight in removing ports. Back in 2009 we had MagSafe, ethernet, Mini DisplayPort, 2x USB, audio, and a security slot.

We'd also remind you to say goodbye to your optical drive, but that ship has pretty much sailed.
